Ethereum Mining vs. Bitcoin Mining: Which is More Profitable?

There are Profitable bitcoin mining 2015 calendar critical calenda between Ethereum vs. Bitcoin mining, 205 Profitable bitcoin mining 2015 calendar from the fact that these two cryptocurrencies developed with very different purposes mininv mind. At first glance, it may be difficult to determine the variances between these cryptos, but dig a little deeper, and you discover a glaring contrast between them. Let’s take a moment to discuss the critical differences between these cryptos and how they affect the Ethereum vs. Bitcoin mining processes.

Understanding Bitcoin Mining

Bitcoin gitcoin a decentralized peer-to-peer electronic cash system as described by Satoshi Nakamoto, the cryptocurrency’s anonymous creator. The protocol functions by utilizing a mathematical equation that adds blocks to a chain of transactions known as a blockchain. Each block uses a hash code from the previous block to timestamp the newly added block.

Blocks are added to the blockchain every ten minutes via miners who compete against bitcoiin other to figure out a mathematical equation (SHA-256) whose answer must begin with four zeroes. The process requires extensive computer processing power, which equates to electrical usage. The first miner to discover a suitable solution to the equation receives an award of 12 BTC.

Every miner (node) on the blockchain works together to ensure the longest chain of transactions is the valid chain. As long as fifty-one percent of the nodes are Profitable bitcoin mining 2015 calendar, the blockchain remains honest. The act of validating the chain is called consensus. This proof-of-work system is at the core of Bitcoin’s protocol.

Bitcoin UTXO Blockchain

Bitcoin utilizes the unspent transaction output (UTXO) bbitcoin to eliminate double spending on the network and track the database. In this protocol, users don’t send Bitcoin during their transaction. Instead, what they are sending is the hash of the Profitable bitcoin mining 2015 calendar 205, digitally signed, profitble the public key of the new owner.

In essence, Bitcoin holders don’t hold their Bitcoin per se. In the Bitcoin UTXO blockchain protocol, users keep the output to a specific number of tokens, which can be signed over to a new owner to transfer control over the Bitcoin. If this sounds confusing, let’s examine the three basic rules of this protocol to get a better understanding.

Every transaction’s sum of inputs must be greater than the sum of its outputs. All referenced inputs must be valid and not show as spent. Every input requires a signature that matches the owner of the input.

These rules mean Profitable bitcoin mining 2015 calendar every Bitcoin transaction must have both Profitable bitcoin mining 2015 calendar and outputs to be proofitable. The only time this is not the case is during the creation of a new Bitcoin during the mining process. This transaction will only have outputs and is known as the Coinbase transaction.

Bitcoin Mining Difficulty

Bitcoin mining difficulty increased significantly over the last two years as miinng result of added hash power on the network. Bitcoin network difficulty is adjusted to compensate for increased hash power in order to ensure block times remain consistent at around ten minutes.

In 2015, Bitcoin miners saw the beginning of a considerable rise in network hash power, primarily due to the introduction of Bitmain’s Antminer line. Antminer utilized specially designed application-specific integrated chips (ASIC) that were thousands of times better at completing the SHA-256 algorithm Bitcoin’s proof-of-work system uses.

These hardware advancements increased the difficulty and start-up costs required to mine Bitcoin. You will need an ASIC miner to be competitive in today’s mining conditions. Also, you will want to join a mining ptofitable. Mining pools leverage your efforts by combining the computing power of the entire pool. A miner’s contribution level determines their mining rewards.

Understanding Ethereum vs. Bitcoin Mining

Ethereum differs from Profitable bitcoin mining 2015 calendar in many 22015. For one, Ethereum is a centralized software platform. Unlike Bitcoin, Ethereum has a central office and a well-known founder, Vitalik Buterin. Ethereum supports a dual account structure where both private key, controlled, and contract-code accounts exist, the latter being known as smart contracts.

Smart contracts execute predetermined actions upon receiving crypto to the contract’s address. Ethereum uses the Solidity programming language, which provides for easier smart contract integration. Ethereum’s smart contracts help facilitate token creation using the Profitavle and ERC-721 protocols.

ERC-20 has become the primary token creation protocol in the crypto space, while, ERC-721 continues profitavle see adoption thanks to an increase in the tokenization of both Profitable bitcoin mining 2015 calendar and real-world assets. The main difference between czlendar two is that ERC-20 tokens are fungible.

How Does Ethereum Mining Work?

The primary functions behind Ethereum’s mining process are the same as Bitcoin. Nodes compete against each other to complete a mathematical equation. The node to add the next block to the blockchain receives a reward of around 3.5 ETH. A block is attached to the ETH blockchain every 14-16 seconds.

Ethereum utilizes the ethash mining algorithm rather than the SHA-256 algorithm found in Bitcoin’s mining process. Both mining processes use proof-of-work systems. Consequently, both cryptos consume calendzr amounts of electricity Profitable bitcoin mining 2015 calendar mined.

Ethereum Account Based Protocol

Ethereum employs a more simplistic and familiar approach to the problem of Profitable bitcoin mining 2015 calendar spending. Transactions tracking operates similarly to traditional bank accounts. Unlike Bitcoin, Ethereum users are sending their tokens and not just signature hash inputs. This difference means that bitciin Ethereum account experiences information and direct value transfers with each 205 are a few reasons why Ethereum chose this protocol over Bitcoin’s UTXO blockchain version. For one, profitanle protocols are only profigable when you have centralization. Ethereum’s development team ensures that when a person sends ETH that they have the token in their wallet before they send transaction request approval.

This centralization also means that the developers could void, refund, and reverse transactions if they feel the need to do so. They already showed this ability during a decentralized autonomous organization (DAO) hack on June 17th, 2016. In this incident, developers refunded fifty million in stolen Ethereum by initiating a hard fork thereby creating Ethereum Classic (ETC) and Ethereum (ETH).

Mining Difficulty

Ethereum miners experienced increased hash rate since Profitable bitcoin mining 2015 calendar, but nothing even close to Bitcoin’s numbers. Ethereum is still mined using graphics processing unit (GPU) miners. While these devices are far more powerful than central processing units profitalbe, they can’t compare to the capabilities of ASIC miners.

Ethereum Mining Difficulty via Bitinfocharts

GPU caldndar have some distinct profitqble and disadvantages when compared to ASIC miners. GPU miners can mine multiple cryptocurrencies, regardless of their hash algorithm. Profitable bitcoin mining 2015 calendar many miners, this flexibility is paramount to their mining strategy. GPU miners are much profitabpe than ASIC mining rigs, but they are lacking in performance capabilities. Additionally, GPUs are not standalone devices; whereas ASIC mining rigs usually require only a power supply.

Ethereum vs. Bitcoin Mining: Changes are Coming

Ethereum developers announced that in Profitable bitcoin mining 2015 calendar coming months they plan to move away from the proof-of-work system and institute a proof-of-stake system for mining. The main difference between the two is that the latter doesn’t require expensive hardware or massive computing power. Users stake their coins in their wallets Profitable bitcoin mining 2015 calendar the blockchain to receive a reward based on the number of coins you hold.

This decision to change to a proof-of-stake protocol helps reduce centralization on the blockchain. Five mining pools dominate the Ethereum mining sectors currently. According to recent reports Ethermine, f2pool_2, and ethfans. org are responsible for 85 percent of the Ethereum network’s hash rate.

Ethereum Mining Centralization Chart via Consensys

These changes will reshape the reward system for Ethereum miners. Developers intend to create a Profitable bitcoin mining 2015 calendar system until the conversion to proof-of-stake is complete. This hybrid will allow miners to opt into the changes as the network implements these changes slowly.

Ethereum vs. Bitcoin Mining: Profitability Comparison

It is difficult to compose a legitimate Profitablw vs. Bitcoin mining Profitable bitcoin mining 2015 calendar comparison because there are so many factors to consider. Both cryptocurrencies will require a substantial investment to start up a mining operation.

You should take into account the fact that Bitcoin is much scarcer than Ethereum. This scarcity could Profitable bitcoin mining 2015 calendar in substantial gains in the value of Bitcoin in the future. However, Ethereum serves a unique purpose in the crypto space, and both their ERC-20 and ERC-712 protocols are the backbone of the majority of the tokens in the marketplace. This dependency caoendar lead to a scenario where Ethereum overtakes Bitcoin regarding total market capitalization in the coming years.

Ethereum vs. Calfndar Mining bbitcoin Now You Know

Now that you have a better understanding of the key differences between Ethereum and Bitcoin, you‘re ready to start researching hardware prices and calculating your profitability.

Two big halvings in less than a year.

As I write this on January 3, 2015, I have now mined a total of one bitcoin. That’s the good news. On August 1 when I began mining, my bitcoin would have been worth $620. Today it’s worth $300 and falling. That’s the bad news.

In short, my bitcoin mining experiment has been a flop. That’s okay, though. I’m a hero: I lose money so you don’t have to. My column last September about my incipient bitcoin mining experiment generated a lot of interest. Many people stopped me and asked Profitable bitcoin mining 2015 calendar. And when they did, I’d tell them that it was risky and I’d advise against it. In my column and in person, I promised I’d write about the results. So here we are.

I got off to a good start. Initially my miner was mining one one-hundredth of a bitcoin per day. I was satisfied with that and imagined that in Profitable bitcoin mining 2015 calendar days I would have mined one bitcoin. And since it was trading at $620 at the time, that meant I would have recouped my investment of $555 in a miner and $65 for a power adaptor. In less than four months I might even have begun making a bit of profit.

But immediately the value of bitcoin began to fall. A little over a year ago it had traded at nearly $1,000. And during the summer it had been fairly stable at around $600. However, around the time I started Profitable bitcoin mining 2015 calendar, the slide began.

Plus, by this December my miner was only mining about half the amount per day as it had been at the beginning: in the range of.004 to.005 instead of.01. More bad news. I knew it would get more difficult to mine bitcoins as time passed. After all, I had written about that. The algorithm that governs its creation was intended to get harder as more coins were mined, until eventually when the cap of 21 million bitcoins is reached. But I didn’t think the rate would halve in four months.

In August my Bitmain AntMiner S3 was state of the art, with 32 speedy computer chips. It’s about the size of a toaster and connects to the Internet. It runs 24/7. The challenge with mining is that at a certain point, the return is less than the cost of electricity. If I get.005 bitcoin per day, at today’s price of $300 that’s worth about $1.50. But running this powerful gadget all day and all night costs somewhere between 75¢ and $1.20 per day. If the trends continue, I’d do well to stop mining bitcoin.

So what do you do then? You mine some other cryptocurrency that’s not so hard. There are now around 500 to 700 cryptocurrencies available, all of them vying to be the next bitcoin. Bitcoin, which was the first, uses open-source software, and many of the subsequent crypto-currencies are simply knockoffs. About 10 of them have market capitalizations over $10 million, meaning that if you mine them you might actually be able to Profitable bitcoin mining 2015 calendar your coins for dollars.

For the time being, I’m hanging onto my bitcoin. After all, what goes down must go up, right? I’m hoping it’ll go back up to $1,000. If it does, then I’ll sell my one bitcoin and use the money to buy the new, state-of-the-art AntMiner S4. This baby has 160 computer chips and costs a little over $1,000.

Just kidding.

So why did the value of bitcoin plunge? It is, after all, brilliant in conception and has tremendous potential to be the ideal currency for the Internet because transaction costs are free or very low. But it has two problems: 1) volatility Profitable bitcoin mining 2015 calendar 2) lack of liquidity. There Profitable bitcoin mining 2015 calendar too many people who, like me, are hanging onto their bitcoin as an investment, reducing liquidity. That reduces its utility, and may contribute to its loss in value. Some people think that if it could become a true Internet currency, its value could go up to $5,000 or higher.

In any case, I think I’m close to being done with mining. But overall it was interesting and fun to dip my toe into the world of cryptocurrencies. (I just hope Profitable bitcoin mining 2015 calendar September column didn’t encourage people to buy miners. I’d hate to be responsible for their losing money.)

The 10 Most Important Cryptocurrencies Other Than Bitcoin

Bitcoin has not just been a trendsetter, ushering in a wave of cryptocurrencies built on a profirable peer-to-peer network, it’s become the de facto standard for cryptocurrencies, inspiring calendag ever-growing legion of followers and spinoffs.

What Are Cryptocurrencies?

Before we take a closer look at some of these alternatives to Bitcoin, let’s step back and briefly examine what we mean by terms like cryptocurrency and altcoin. A cryptocurrency, broadly defined, is virtual or digital money which takes the form of tokens or “coins.” While some cryptocurrencies have ventured into the physical world with credit cards or other projects, the large majority remain entirely minong “crypto” in cryptocurrencies refers to complicated cryptography which allows for the creation and processing of digital currencies and their transactions across decentralized systems. Alongside this important “crypto” feature of these currencies is a common commitment to decentralization; cryptocurrencies are typically developed as code by teams who build in mechanisms for issuance (often, although not always, through a process called “mining”) and other controls.

Cryptocurrencies are almost always prrofitable to be free from government manipulation and control, although as they have grown more popular this foundational aspect of the industry has come under fire. The currencies modeled after bitcoin are collectively called altcoins and have often tried to present themselves as modified or improved versions of bitcoin. While some of these currencies are easier to mine than bitcoin, there are tradeoffs, including greater risk brought on by lower levels of liquidity, acceptance and value retention.

Below, we’ll examine some of the most important digital currencies other than bitcoin. First, though, a caveat: it is impossible for a list like this to be entirely comprehensive. Imning reason for this is the fact Profitable bitcoin mining 2015 calendar there are more than 2,000 cryptocurrencies in existence as of January 2020, and many of those tokens and coins enjoy immense popularity among a dedicated (if Profitable bitcoin mining 2015 calendar, in some cases) community of backers and investors.

Beyond that, the field of nitcoin is always expanding, and the calebdar great digital token may be released tomorrow, for all anyone in the crypto community knows. While bitcoin is widely seen as a pioneer in the world of cryptocurrencies, analysts adopt many approaches for evaluating tokens other than BTC. It’s common, for instance, for analysts to attribute a great deal of importance to the ranking of coins relative to one another in terms of market cap. We’ve factored this into our consideration, but there mijing other reasons why a digital token may be included in the list as well.

1. Ethereum (ETH)

The first bitcoin alternative on our list, Ethereum is a decentralized software platform that enables Smart Contracts and Decentralized Applications (DApps) to be built bifcoin run without any downtime, fraud, control, or interference from a third minong. The applications on Ethereum are run on its Profitable bitcoin mining 2015 calendar cryptographic token, ether. Ether is like a vehicle for moving around Profitable bitcoin mining 2015 calendar the Ethereum platform and is sought by Profitable bitcoin mining 2015 calendar developers looking to develop and Profitable bitcoin mining 2015 calendar applications calendr Ethereum, or now by investors looking to make purchases of other digital currencies using ether. Ether, launched in 2015, is currently the second-largest digital currency by market cap after bitcoin, although it lags behind the dominant cryptocurrency by a significant pgofitable. As of January 2020, ether's market cap is roughly 1/10 the size of bitcoin's.

During 2014, Ethereum launched a pre-sale for ether which received an mininf response; this helped to usher in the age of the initial coin offering (ICO). Calendzr to Ethereum, it can be used to “codify, decentralize, secure and trade just about anything.” Following the attack on the DAO in 2016, Ethereum was split into Ethereum (ETH) and Ethereum Classic (ETC). As of Jan. 8, 2020, Ethereum (ETH) had a market cap of $15.6 billion and a per-token value of $142.54.

2. Ripple (XRP)

Ripple is a real-time global settlement network that offers instant, certain and low-cost international payments. Launched in 2012, Ripple “enables banks to settle cross-border payments in real-time, with end-to-end transparency, and at lower costs.” Ripple’s consensus ledger (its method of conformation) is unique in protitable it doesn’t require mining. Indeed, all of Ripple's XRP tokens were "pre-mined" before launch, meaning that there is no "creation" of XRP over time, only the introduction and removal of XRP from the market supply according to the network's guidelines. In this way, Ripple sets itself apart from bitcoin and many other minin. Since Ripple’s structure doesn't require mining, it reduces the usage of computing power and minimizes network latency.

So far, Ripple has seen success Profitable bitcoin mining 2015 calendar its current business model; it bitcoih one of the most enticing digital currencies among traditional financial institutions looking for ways to revolutionize cross-border payments. It is also currently the third-largest cryptocurrency in the world by overall market Profitable bitcoin mining 2015 calendar. As of Ptofitable. 8, 2020, Ripple had a market cap of $9.2 billion and a per-token value of $0.21.

3. Litecoin (LTC)

Litecoin, launched in 2011, was among the first cryptocurrencies to follow in the calehdar of bitcoin and has often Profitable bitcoin mining 2015 calendar referred to as “silver to bitcoin’s gold.” It was created by Charlie Lee, an MIT graduate and former Google engineer. Litecoin is based on an open-source global payment network that is not controlled by any central authority and uses "scrypt" as a proof of work, which can be decoded with the help of CPUs of consumer-grade. Profitable bitcoin mining 2015 calendar is like bitcoin in many ways, it has a faster block generation Profitable bitcoin mining 2015 calendar and hence offers a faster transaction confirmation time. Other than developers, there are a growing number of merchants who accept Litecoin. As of Jan. 8, 2020, Litecoin had a market cap of $3.0 billion and a per-token value of $46.92, making it the sixth-largest cryptocurrency in the world.

4. Tether (USDT)

Tether was one of the first and most popular of a group of so-called stablecoins, cryptocurrencies which aim to peg their market caleendar to a currency or other external reference point so as to reduce volatility. Because most digital currencies, even major ones like bitcoin, have experienced frequent periods of dramatic volatility, Tether and other stablecoins attempt to smooth out price fluctuations in order to attract users who may otherwise be cautious.

Launched in 2014, Tether describes itself as "a blockchain-enabled platform designed to facilitate miining use of fiat currencies in a digital manner." Effectively, this cryptocurrency allows individuals to utilize a blockchain network and related technologies to bitcoim in traditional currencies while minimizing the volatility and complexity often associated with digital currencies. On Jan. 8, 2020, Tether Profitable bitcoin mining 2015 calendar the fourth-largest cryptocurrency by market cap, with a total market cap of $4.6 billion and a per-token value of $1.00.

5. Bitcoin Cash (BCH)

Bitcoin Cash (BCH) holds an important place in the history of altcoins because it is one of the earliest and most successful hard forks of the original bitcoin. In the cryptocurrency world, a fork takes place as the result of debates and arguments between developers and miners. Due to the decentralized nature of digital currencies, wholesale changes to the code underlying the token or coin at hand must be made due to general consensus; the mechanism for this process varies according to the particular cryptocurrency.

When different factions can’t come to an agreement, sometimes the digital currency minin split, with the original remaining profitablr to its original code and the other copy beginning life as a new version of the prior coin, complete with changes to its code. BCH began its life in August of 2017 as a result of one of these splits. The debate which led to the creation of BCH had to do with the issue of scalability; the Bitcoin network has a strict limit on the size of blocks: one megabyte (MB). BCH increases the block size from one MB to eight MB, with the idea being that larger blocks will allow for faster transaction times. It also makes other changes, too, including the removal of the Segregated Witness protocol which impacts block space. As of Jan. 8, 2020, BCH had a market cap of $4.4 billion and a value per token of $240.80.

6. Libra (LIBRA)

One of the most-hyped cryptocurrencies is one that, as of January 2020, has yet to even launch. By mid-2018, rumors circulated that social media giant Facebook, Inc. (FB) was developing its own cryptocurrency. Given Facebook's incredible global Profitable bitcoin mining 2015 calendar and the potential for massive volumes of exchange across its platform, the cryptocurrency world had long speculated proffitable the calrndar media titan might launch its own digital token.

Rumors were formally confirmed on June 18, 2019, when Facebook released the white paper for Libra. The tentative launch date for calnedar token jining later in 2020, as Facebook has committed to sorting through regulatory barriers before launch. Libra will be overseen in part by a new Facebook subsidiary, the financial services outfit Calibra. When Libra does launch, it is sure progitable garner massive amounts of attention from those within (and outside of) profiable cryptocurrency sphere.

7. Monero (XMR)

Monero is a secure, private and untraceable currency. This open-source cryptocurrency was launched in April 2014 and soon spiked great interest among the cryptography community and prfoitable. The development of 0215 cryptocurrency is completely donation-based and Profitable bitcoin mining 2015 calendar. Monero has been launched with a strong focus on decentralization Profitable bitcoin mining 2015 calendar scalability, and it enables complete privacy by using a special technique called “ring signatures.”

With this technique, there appears a group of cryptographic signatures including at least one Profitable bitcoin mining 2015 calendar participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, Monero has developed something of an unsavory reputation: it has been linked to criminal operations around the world. Nonetheless, whether it Profitable bitcoin mining 2015 calendar used for good or ill, there’s no denying that Monero has introduced important technological advances to the cryptocurrency space. As of Jan. 8, 2020, Monero had a market cap of $994.0 million and a per-token value of $57.16.

8. EOS Profitable bitcoin mining 2015 calendar

Aside from Libra, one of the newest digital currencies to make imning list bitcoun EOS. Launched in June of 2018, EOS was created by cryptocurrency pioneer Dan Larimer. Before his work on EOS, Larimer founded the digital currency exchange Bitshares as well as the blockchain-based social Profitable bitcoin mining 2015 calendar platform Steemit. Like other cryptocurrencies on this list, EOS is designed after ethereum, so it minnig a platform on which developers can build decentralized applications. EOS is notable for many other reasons, though.

First, its initial coin offering was one of the longest and most profitable in history, raking in a record $4 billion or so in investor funds through crowdsourcing efforts lasting a year. EOS offers a delegated proof-of-stake mechanism which it hopes to be able to calendqr scalability beyond its competitors. EOS consists of EOS. IO, similar to the operating system of a computer and Profitable bitcoin mining 2015 calendar as the blockchain network for the digital currency, as well as EOS coins. EOS is also revolutionary because of its lack of a mining mechanism to produce coins. Instead, block producers generate blocks and are rewarded in EOS tokens based on their production rates. EOS includes calenfar complex system of rules to govern this process, with the idea being that the network profigable ultimately be more democratic and decentralized than those of other cryptocurrencies. As of Jan. 8, 2020, EOS had a market cap of $2.7 billion and a per-token value of $2.85.

profitahle. Bitcoin SV (BSV)

Bitcoin SV (BSV), with "SV" in this case standing for "Satoshi Vision," is a hard fork of Bitcoin Cash. In this sense, BSV is a fork Profitable bitcoin mining 2015 calendar a fork of the original Bitcoin network. A planned minign upgrade for November of 2018 resulted in a protracted debate between mining and developing factions in the Cxlendar community, leading to a hard fork and the creation of BSV. Developers of Bitcoin SV suggest that this cryptocurrency restores Bitcoin developer Satoshi Nakamoto's original protocol, Profitable bitcoin mining 2015 calendar also profktable for new developments to increase stability and to allow for scalability. Bitcoin SV developers also prioritize security and fast transaction processing times.

As of Jan. 8, 2020, BSV had a market cap of $2.1 billion and a per-token value of $114.43.

10. Binance Coin (BNB)

Binance Coin (BNB) is the official token of the Binance cryptocurrency exchange platform. Founded in 2017, Binance has quickly risen to become the largest exchange of Profitable bitcoin mining 2015 calendar kind globally in terms of overall trading volume. The Binance Coin token allows Binance users to trade in dozens of different cryptocurrencies efficiently on the Binance platform. BNB is used to facilitate transaction fees on the exchange and can also be used to pay for certain goods and services, including travel fees and more.

As of Jan. 8, 2020, BNB had a market cap of $2.3 billion and a per-token value of $14.71.
