It says that there will only ever be 21 million Bitcoin and the current BTC supply is almost at 19,094,150. What happens when its limit reached? will BTC price goes up instantly due to scarcity? is it the doom for Bitcoin since there is no room to mine? or maybe it will likely never reach 21 million?
According to me, fiat currency is showing it's flaws at regular intervals and that is making more people to believe that an alternate system of payment is needed.
Though bitcoin is not perfect but it still shows how people can actually have a control on their money and literally own their wealth.
Bitcoin is a gateway to an alternate payment method and this is enough reason why I can say that it will continue to exist forever.
People who can afford it will hold it while other alternate currencies would be used for daily payments.
So even after all the bitcoins are mined people will still use it and miners will rely on the mining fees for rewards.
