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?
When the whole bitcoin have been mined there's nothing to worry about, the orice and value of bitcoin remains and here miners get their rewards from the incentives of the transaction fees levied on every transaction made, the volatility is neither a threat to waether bitcoin in failing but by then, it will still be maintained as that's what drive the push for buying and selling of bitcoin in the market, the price is likely to go high drastically because the more the adoption the higher it's demand and price will indeed increases as well.
