What happens if someone loses their bitcoin? Let's imagine that I buy 10,000,000 bitcoin for example. Does the system need to re-create those money?
First, it is next to impossible to lost bitcoin because it is the digital currency and it remains into ur wallet and no-one is able to steal it unless you share your blockchain password to anyone but if accidentally u lost ur BTC, it's impossible to recover it because it's not the paper currency that u can recover it because there are limited number of BTC that has been created and these BTC are keep on circulating, so once you lost them it's next to impossible to recover them.
