I think bitcoin is officially called currency or legit currency because government can't regulate it. They don't have access on bitcoin which is a decentralized platform. If we expect bitcoin to become a legit currency then bitcoin will need to be regulated to be accepted internationally.
Many of us wanted bitcoin becomes legit like in other country, but in us this is not regulated in our country philippines due to some circumstances our government cannot controlled it like spammers and scammers it is too risk for our government thats why it is not legit in here ..
