People need loans (bank loans atm) to live. To buy a car, a house, school, etc. Our society only works with loans.
So, if bitcoin becomes HUGE, how will unroll the bitcoin loans?
not all people need loans so don't take it as a whole that our society works with loans. If bitcoins became huge then maybe loaning will be not that hard to get or maybe the other way. Depends on the person loaning and the one who is asking for it.
