I really do not like the fact that I can not use it everywhere I want to spend money. It is very convent for me to access my bitcoin accounts and get my money, but because everyone does not accept the currency, it complicates things.
this is not a big problem any more. bitcoin is not accepted in a lot of places but bitcoin is convertible currency. you can get any currency of the world in return of bitcoin. and spend it anywhere..
and nowadays there is a lot of bitcoin related debit/credit cards working here. you can get a card and spend your bitcoin at any places..
