But I do not think that bitcoin at the legislative level can become the official world currency.Some States have a negative attitude towards cryptocurrency.And in every possible way hinder its progress or impose restrictions on its use.Bitcoin has many advantages and it has all chances for life. This will help to move the world economy forward.
Yes that is true bitcoin can already be called an international currency because they make payments in any state.
And yes bitcoin are many advantages and very profitable currency to many people that will gives opportunity to unfortunate person.
