There is a fixed supply of 21 million Bitcoin Image: Shutterstock. Like many other cryptocurrencies, Bitcoin BTC was designed around the principle of a finite supply. For other cryptocurrencies , this cap can vary considerably—ranging from as low as Bitcoin's limited supply is a huge advantage. It keeps the cryptocurrency scarce, theoretically ensuring that its value holds steady for years to come.
It's for this reason that Bitcoin is often called "digital gold"; like gold, there's only a certain amount of Bitcoin in existence. By limiting its maximum supply, and slowing the rate at which new Bitcoin come into existence, Satoshi intended each individual Bitcoin unit known as a satoshi to appreciate in value over time. According to an email purportedly shared between Nakamoto and Bitcoin Core contributor Mike Hearn, Satoshi reasoned that if 21 million coins were to be used by some fraction of the world economy, 0.
Although Satoshi compares the price of Bitcoin to the Euro in his email, some simple mathematics indicates he may have had a much grander vision for Bitcoin—better explaining why the 21 million maximum figure was chosen. This figure, known as the M1 money supply, is made up of the total value of all the physical money in the world, including cash, coins, travelers' checks, and more.
Although the M1 money supply replacement theory is perhaps the most plausible rationale for why Satoshi selected 21 million to be the cap for Bitcoin, there is another—somewhat simpler—possible explanation. Looking at the parameters used to control Bitcoin's supply, it becomes clear that the 21 million BTC figure allows the network to ensure that blocks are mined in a regular timeframe 10 minutes.
It also ensures that the amount of Bitcoin paid out to miners as block rewards decreases over time, as the maximum supply approaches its limit. A key consideration is that once the supply of new bitcoin is shut off, any increase in demand would place upward pressure on the price.
Further, investors may perceive Bitcoin as being more scarce than before once the supply hits its limit. While the Bitcoin Protocol capped the total number of bitcoin that can be mined, this limit is not expected to be reached until approximately While the supply is expected to change between now and , it is not expected to change a whole lot.
As to how reaching the 21 million cap will affect miners, no one knows for sure. However, one thing we do know is that unless the Bitcoin Protocol changes, miners will no longer receive the block reward once the cap is reached. At that point, they will be incentivised by transaction fees, which may be enough to keep miners interested.
If the number of miners decreases significantly, it could undermine the security of the Bitcoin network. This could then reduce the public perception of the world's largest digital currency, making it less appealing to investors and placing downward pressure on its price. One development that could potentially affect this situation is the implementation of Segregated Witness SegWit , an upgrade that allows blocks in Bitcoin's blockchain to store a greater number of transactions.
By increasing this amount, SegWit enhanced the capacity of the Bitcoin network. Further, this update coincided with reduced transaction fees. When the Bitcoin network rolled out SegWit, it laid the foundation for the Lightning Network, which enables off-chain transactions. Bitcoin's supply is capped at 21 million, and it is uncertain how reaching this limit will affect the digital currency's price. By removing the mining reward, hitting this limit could discourage miners from participating.
This could then make the network less secure, negatively affecting sentiment and therefore lowering prices. At the same time, Bitcoin's price could benefit from its supply hitting its upper limit. Once the supply is fixed, any increase in demand would place upward pressure on prices.
Further, reaching a hard cap on the total number of bitcoin available could contribute to the perception that the digital currency is a scarce resource, potentially pushing prices higher.

Anatol Antonovici Feb 27, It is not a secret that Bitcoin is one of the scarcest assets out there. But have you wondered how rare the largest cryptocurrency really is? Imagine if a new global regime would rise out of nowhere to rule the world through a UN-like body and decided that everyone should be equal. More than that, this new body would endorse Bitcoin as a legitimate currency and would distribute it to everyone.
That means that each person would end up with 0. Not that much, right? This demonstrates that there is still much room left for Bitcoin adoption. It is expected that all of the total supply of 21 million coins will be in circulation by The world population by that time is expected to be That means that every individual would get 0.
You should take into account that we ignored companies, legal persons, institutional investors, governments, and all kinds of organizations that might also own Bitcoin. However, the USD supply also involves digital dollars. Think about bank deposits, online transfers, and all the fiat dollars held digitally. What do you think about the Bitcoin scarcity?
