For me the problem has to do with global acceptance and we'll get there one day. It needs to be accepted by world governments in order to erase the fear of usage from non users.
Exactly i am also looking for the same thing if our government will accept this Bitcoin as a legal currency. We can freely use bitcoin for all purpose. The main problem is we can not use Bitcoin directly in my country I have to exchange my BTC to fiat currency they will charge high currency this is the problem we are facing in our country.
