Trust is a key issue in whether bitcoin can become a global currency, and if everyone trusts him, it can be used to make money.
But who in reality can trust bitcoin completely? Does anyone change all of their money into bitcoin?
If you want something you will have to invest three things, your capital, your patience to hold and your trust for bitcoin to get huge profit, bitcoin is getting legal in a lot of countries which is the sign that bitcoin will become the world legal currency ad it will increase high in price, so more countries will announce bitcoin as legal currency,. To me the increasing demand and the high acceptance will help us to make bitcoin global currency, as bitcoin is famous worldwide but we are just waiting for the worldwide acceptance.
