You don’t need 51% of the world’s power though, just 51% of the power of people who care about how the system works. Most people using block chain cryptos don’t care at all, so the threshold is a tiny percentage of the user base.

It works more like loaning money and then receiving interest, except you are loaning crypto to the network and then you get it back, plus some, after a certain period of time
