plus there aren't enough resources where they can spend their bitcoins because not many places accept bitcoins till now
There isnt any country yet that has "enough resources" for you to spend your
BTC either. This is the hard truth about
BTC however if Greece was to adopt
BTC then that could change as the whole country will be shifting to
BTC but do note that this will not be the extreme solution for them because their problem will be pretty much unsolved already
and there is a high risk of losing these by being hacked
BTC is not unhackable , every wallet that is connected to the network is not safe at all and it is pretty normal. The same thing with holding FIAT as you are exposing yourself to be robbed as well .
