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?
The system will not create another bitcoins just to cover up what you lost. Bitcoin has a limited supply which makes bitcoin valuable and if you lose a big amount af bitcoib and didn't recover it,it will bring the bitcoin price increase if there is a huge demand. Because if the demand is higher and the supply is short then the price also increased.
