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?
Bitcoin is already a global currency since it has been used by people worldwide but it often used as a store of value more than a currency that is being used daily.
With regards to loans, this is where signed address, escrow services and possibly collaterals will enter. Ohh wait add also Blockchain in the show because you can easily track the borrowers with just their Bitcoin address. Escrow services helps you with the transaction and if there is a collateral involved with the transaction of the lender and borrower then better.
