if bitcoin does become a global currency between the world. how would things like loans, renting ourt apartments work? what if somebody doesnt pay back what he’s owed , can they aftually track to verify that he has not paid?
I am not entirely convinced that BTC would be a global currency of exchange, it would certainly become a store of value. Alt-coins, with smart contract programmability would be more likely to be the unit of exchange, for things like loans, renting out apartments, or payroll for work. Alt-coins just has the flexibility to dynamically exchange value, where Bitcoin has the static capability to store a value.
