Bitcoin mining 21 million limited. How Many Bitcoins Are There? How Many Left to Mine? (2020). What Happens to Bitcoin After All 21 Million Are Mined?

Bitcoin halving: what to expect?

We are reaching peak Bitcoin and this is going to change the whole ecosystem. Some even think that it could be the end of Bitcoin as we know it.

As programmers we have to admire the algorithm that Bitcoin relies on. It's not perfect, but it is clever and it works most of the time. However when Satoshi Nakamoto, whoever he is, proposed Bitcoin he limited the total number to 21 million coins. It is generally said that this is an anti-inflationary rule, although how you measure inflation in Bitcoin mining 21 million limited cryptocurrency that is as volatile as Bitcoin is a good question.

The idea was that Bitcoin miners would be rewarded for their efforts by newly-minted Bitcoin. This would pay for the computational efforts needed to maintain the Blockchain. This processing in return for new Bitcoin is generally referred to as "Bitcoin mining", although any earth moving happens miles away to feed power stations. After eleven years, yes the paper Bitcoin: A Peer-to-Peer Electronic Cash System was published on October 31, 2008, we are now Bitcoin mining 21 million limited a position where over 85% of the total Bitcoin have been mined. There are still 3 million or so Bitcoin to be mined and this should keep things going for a while, but there are other factors. The first is that every 210,000 blocks the Bitcoin reward halves. This is set to happen in May 2020 at the current mining rate. This halving means that it will take until 2140 to completely run out of Bitcoin, but notice that this also means that the reward to miners goes down.

It seems likely that the value of each Bitcoin will go up as we approach peak Bitcoin, but if the reward to miners is going to stay roughly the same, a single Bitcoin has to appreciate to roughly $125,000 and this seems less likely, although some are regarding it as a Bitcoin mining 21 million limited bet.

The problem is that the most likely scenario is that miners' profits are set to fall and Bitcoin mining 21 million limited go to zero and their costs are almost certain to go up as the hash difficulty level increases to take account of increasingly powerful hardware.

So who is going to process Bitcoin when it is unprofitable?

The simple answer is the same miners who are doing it at the moment and Bitcoin users are Bitcoin mining 21 million limited to have to pay for this in transaction fees. As it is you can already offer miners a transaction fee to speed your transaction through. All this means is that the miners preferentially pick transactions with fees to include in the block they are mining. This sounds reasonable, but a new study from Cornell suggests it has negative effects:

“Bitcoin now works essentially how markets work, because if you want something to happen faster, you have to pay for it.

According to one of its authors, Maureen O’Hara, the Robert W. Purcell Professor of Finance:

“Transaction fees are not part of the original system – they just evolved. A system that’s designed by a computer scientist for security problems may not be well-designed to trade in the markets, so the development of fees is actually a good thing. But it also created all kinds of problems.”

The problem is that transaction fees easily become a significant part of the total Bitcoin mining 21 million limited to the end user meaning that Bitcoin becomes unattractive for all but large purchases. As part of the study an economic model was developed to predict transaction costs. Basically the conclusion is that transaction costs Bitcoin mining 21 million limited rise to the point where users are waiting Bitcoin mining 21 million limited as long as they were before the transaction costs.

It is clear that as we approach peak Bitcoin transactions fees will increase and Bitcoin will become even less attractive for small transactions - which is a pity as this was Bitcoin mining 21 million limited of the early hopes for Bitcoin.

Total Number of Bitcoins

How Many Bitcoins are There? – 85% of the world’s Bitcoin has been mined

The popularity of Bitcoin is tied to the fact that its limit is capped at 21 million bitcoins in total. The original blockchain cannot mint new coins nor burn existing coins in the supply. The only way new coins are created is through mining however, even with time, the amount of bitcoin released via mining decreases until it reaches its cap.

In this guide, we will look into how many Bitcoins are there, understand what limits are placed on Bitcoins supply, the purpose behind it and the current count of Bitcoins in circulation and of course, some speculations as to what entails beyond the end of Bitcoin’s supply. Let’s dig in.

How many Bitcoins are currently in circulation as of 2020?

As of 2020, there are just over 18 Million Bitcoins in existence. However, not all of them are actually usable. Among those 18 million, approximately 4 million bitcoins are lost whereas, around 1 million were stolen in various hacks and heists such as that of through Mt. Gox. That leaves us with 13 million bitcoins. Well hold on, do not forget the “Whales”! Whales are people who own a huge number of bitcoins stashed away in their wallets. Among these whales is the founder of Bitcoin, Satoshi Nakomoto, whose public address is home to about 1 million bitcoins which are roughly worth 10 billion US dollars.

As of today, about 5 million of bitcoin belong to around 1600 whales. That’s about 28% of the total circulation. After taking away all these unreachable coins, Bitcoin mining 21 million limited left with a mere 44% of the total technical bitcoins in existence. That’s about 8 million in total.

What are Limits on Bitcoin Circulation?

By design, the bitcoin blockchain is built to only release a fixed number of bitcoins and that through as well through mining. With time, the rewarded bitcoins are halved, and this process is known as bitcoin halving. At the Bitcoin mining 21 million limited of inception, among the first-ever blocks that were mined, the block reward stood at a whopping 50 BTC. However, at that time, it had merely any monetary value associated with it.

The mining reward is structured to decrease after every 210,000 mined blocks. Since the combination of block difficulty and solving time is somewhere around ten minutes, therefore, it takes around 4 years to reach the halving point. Based on these calculations, every four years, the reward is cut into half until there is essentially no reward for bitcoins. That is, in about 120 years from now, in the year 2140, the nodes will have effectively mined all 21 million bitcoins reaching the maximum supply.

How long does it take to mine 1 Bitcoin?

On average, one Bitcoin is mined every 10 minutes, and the rigs involved in creating a new block split the reward amongst themselves. Currently, this reward is currently set at 12.5 Bitcoin but will change due to halving. The speed of mining depends very much on the equipment you are using

Where do We Currently Stand with Bitcoin Circulation and Mining?

Currently, in 2020, the mining rewards is set at 12.5 BTC per block mined. Since the launch in 2008, it has halved two times already in 2012, 2016 and now set to half in July of this year reducing the reward further to 6.25 BTC per Bitcoin mining 21 million limited that is mined.

Currently, the total mined bitcoin or in existence is somewhere around 18 Million. That’s a huge quantity and very much close to the cap of 21 million. This means Bitcoin mining 21 million limited have mined over 85% of the total supply of bitcoins already. But since Bitcoin mining 21 million limited reward decreases over time, therefore, the remaining 20% will be spread over the next 120 years whereas, the early 80% was mined in a span of a mere 12 years!

Since a new block is added every 10 minutes to the blockchain, and each block as of now produces 12.5 BTC, therefore, everyday 1800 Bitcoins are being minted or mined. The calculation of per day mining is pretty simple. We know, there are 60 minutes per hour and 24 hours per day giving a total of 1440 minutes and since it takes 10 minutes to mine one block, therefore, in a day 144 blocks are mined.

24 * 60 / 10 = 144 BLOCKS MINED

To calculate the current per day mining rate, you just multiply 144 by the current reward size. We get 144 * 12.5 = 1800 Bitcoins mined per day! This means per year, we mined 657,000 BTC and after the halving in June, this rate will reduce to 900 per day and 328,500 BTC mined per year.

Why do These Limits Exist Anyway?

You might find yourself wondering why Satoshi Nakomoto thought it would be good to limit the supply of Bitcoins. The concept behind this Bitcoin mining 21 million limited to establish an automatically adjusted balance of supply and demand. The concept of Bitcoin emerged as a strong Bitcoin mining 21 million limited or more so a remedial structure of transactions to the centralized banking system. One major flaw of the conventional banking system is the ability of the bank to curb or dilute the supply of money in Bitcoin mining 21 million limited market, therefore, controlling the purchasing power, inflation and economic conditions along with it.

Bitcoin, on the other hand, aimed to establish a decentralized form of a network where no entity could influence in of itself the supply of the bitcoins, therefore, creating an automatically adjusting supply of bitcoins through capped supply and diminishing rewards.

Let’s take loan proof by contradiction to prove our point here. If for instance, the supply was not capped, the chances of bitcoin gaining substantial rapport as a store of value and investment vehicle would not have been possible. In fact, given its infinite supply, people would have continued to mine as much as they want. Similarly, if the supply was Bitcoin mining 21 million limited capped but the mining block reward did not decrease geometrically, but rather remained constant, it would have taken merely 8 years for the supply cap to have reached. Keep in mind, that currently, it’s been 12 years since its inception and now the general adaption is coming closer to reality. Had it ended in 8 years, the early adopters would have mined all the BTC and left nothing for the rest of the enthusiasts, slowly Bitcoin mining 21 million limited the idea of digital currency along with it.

So, to put things into Bitcoin mining 21 million limited, Satoshi Nakomoto definitely did put in great thought into selecting the right timeframes, declining the mining rate and choosing to put a finite limit on the supply for Bitcoin. Now you may ask, the code is open-source, someone can just tweak that limit. Well, it’s not that easy. You can change the supply but if the majority of the nodes Bitcoin mining 21 million limited not accept the change, it will result in hard fork, leading to some or most of the nodes choosing to stay with the original chain and the new forked chain ultimately dying out due to lack of interest.

Furthermore, if Bitcoin mining 21 million limited were to maliciously attempt to forge bitcoins, that is something that will not end well either. Since at each time, it is possible to correctly estimate the number of bitcoins in circulation (thanks math!), any additional coin added to the supply will stand out and be easily traceable to not-from-the-block origins. So, yes. It is not that easy to just change the code. As the network grows, it just gets exponentially harder to do so.

What happens when all Bitcoins are mined?

There are many speculations regarding that. With every halving as well, technically the worth of circulating bitcoins left tends to spike, indicating a rush of interest Bitcoin mining 21 million limited the ever-declining supply of BTC, However, an ultimate end to the reward mechanism may have interesting implications.

Once Bitcoin mining 21 million limited the bitcoins have been mined, transaction fees will be the sole source of income for miners. The main concern, Bitcoin mining 21 million limited, is whether or not transaction fees will be enough to keep miners financially afloat.

Since rewards are (partially) what motivates a node to continue to validate transactions apart from mining fees, it is among the speculation that miner concentration may reduce or adversely, the mining fees may Bitcoin mining 21 million limited discouraging users to continue to transact in BTC.

Conclusion

However, it is not necessary that the end of supply must mark negative consequences. With a known limited supply of the cryptocurrency, it can appreciate in value and become a safe-haven investment falling in the basket of investment vehicles like gold and other precious metals. It is also possible that developers might agree to unanimously increase the supply to maintain the stability of the network.

It sure is a farfetched thought, over 120 years to be exact, to speculate on the situation that would arise Bitcoin mining 21 million limited of depleted supply of Bitcoin, but it definitely gives rise to interesting theories. What are your thoughts?

The Days Of Bitcoin Mining Are Nearly Over

Why is Bitcoin Capped at 21 Million? Why Can’t It Be Changed?

There will only be 21 million Bitcoins in existence, forever! It is a “hard cap” or maximum supply and it plays a pretty large part in the valuation of any cryptocurrency.

In a centralized economy, the currency is issued Bitcoin mining 21 million limited a central bank at a rate that is supposed to match the growth of the number of goods. The monetary base is controlled by a central bank, that can increase the supply by issuing more currency.

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, the currency is created by the nodes of a peer-to-peer network. Bitcoin mining 21 million limited Bitcoin generation algorithm defines, in advance, how the currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

So, how can we be certain that there can be no more than 20 million Bitcoins? And, why can’t it be changed? Read on….

Why 21 Million?

The overall supply of a coin can be broken down into 3 main parts: Circulating Supply, Total Supply, & Maximum Supply.

Circulating Supply

Bitcoin mining 21 million limited

Total Supply

Maximum Supply

Bitcoin mining 21 million limited,

What is the maximum number of Bitcoins that will ever enter circulation? The 21 million supply cap is Bitcoin’s best-known feature. And this hard cap cannot be changed as it is part of Bitcoin’s core features and code. In other words, crypto inventor Satoshi Nakamoto set a monetary policy based on artificial scarcity at bitcoin’s inception that there would only ever be 21 million coins in total.

Technical Explanation

One of the reasons was the need to keep the number of Satoshis within the limits of 64-bit double floating numbers with a small margin for multiplication/division rounding.

64 bit floating gives 52 bits of explicit storage. Interestingly 2 to the power of 51 is 2,251,799,813,685,248 units. This is just enough to store 21 million coins times 108 divisions.

Mathematical Explanation

Calculate the number of blocks per 4-year cycle:

6 blocks per hour

Sum all the block reward sizes:

Multiply the two:

Economically, because the currency is effectively infinitely divisible, then the precise amount doesn’t matter, as long as the limit remains fixed.

Since Bitcoin is often compared to gold, total coins match the total amount of gold mined in human history which can be imagined as a cube 21 m on a side.

As it is not entirely so important how many Bitcoins will exactly be mined. Satoshi could have easily chosen almost any number. He could just adjust block reward halving (210 000 blocks), reward sizes (50, 25, 12.5 …) etc. to match some Bitcoin mining 21 million limited number.

How Many Bitcoins Are Left?

The remaining coins not in circulation are in a pool dedicated to rewarding miners for maintaining the integrity of the network. As Bitcoin mining 21 million limited validate transactions and create new blocks, they receive the remaining coins from this pool as a reward. The Bitcoin source code outlines how the mining Bitcoin mining 21 million limited should be distributed and when these distributions occur.

There are currently 17 300 900 BTC in existence. This number changes about every 10 minutes when new blocks are mined. The reward for mining each block started at 50 BTC and has since “halved” twice. The current reward sits at 12.5 Bitcoins per block.

144 blocks per day are mined on average, and there are 12.5 BTC per block. 144 x 12.5 is 1,800, so that’s the average amount of new coins mined per day.

Because many miners are adding new hashpower, over the last few years blocks have often been found at 9.5-minute intervals rather than 10. This creates new coins faster, so on most days, there are actually more than 1,800 new Bitcoins created.

Nakamoto’s protocol also requires that the mining reward is halved every 210,000 blocks or approximately four years. The next miner halving will take place within two years, approximately in 2020 depending on the hash rate, bringing the rewards down to 6.25 BTC per mined block.

What Happens When 21 Million Bitcoins Are Mined?

Once miners have unlocked 21 million of Bitcoins, the planet’s supply will essentially be tapped out, unless Bitcoin’s protocol is changed to allow for a larger supply. Sceptics have even proposed that it is theoretically possible to increase Bitcoin’s hard capped supply via a 51 percent or a Sybil attack, but so far neither of these manipulations has proven feasible in the case of BTC.

After 64 total halvings, there will be no more Bitcoins left to reward miners and all 21 million BTC will be in circulation. This will occur sometime in 2140.

Right now, miners earn most of their income via the block reward. When all BTC are mined, there Bitcoin mining 21 million limited be a block reward to pay to miners. When Bitcoin mining 21 million limited user sends a BTC transaction, a small fee is attached. These fees go to miners and this is what will be used to pay miners instead of the block reward, and the transaction fees should be high enough of an incentive for miners to continue running the network (transaction fees should increase dramatically).

As BTC price rises, the value of transaction fees will increase. First, because cryptocurrency becomes more valuable and second because people are willing to pay more in fees in order to get their transaction confirmed faster. However, in order for this increase to be enough for transaction fees to Bitcoin mining 21 million limited mining on its own, the value of Bitcoin will have to increase substantially.

Bitcoin has already seen massive hikes in price in just the past few years. While no one is entirely sure the crypto-financial world, it seems likely that a limited Bitcoin mining 21 million limited of the currency may cause prices to continue to increase. There are supplies of inactive coins that are held around the world, the largest supply of which belongs to mysterious Satoshi Nakamoto.

Conclusions

To conclude, there are several different ways that Bitcoin mining can remain profitable after the block reward goes away. However, this isn’t something we have to worry about at the moment. This is still over a century away!
