Money is a belief system. Much like religion.
If you believe that the best money will become the most popular money, then there's nothing to do but wait and educate.
Most people don't choose their beliefs. Rather they adopt the beliefs of the people around them.
Even those that do choose their beliefs might only make changes once or twice in a lifetime.
Identify those who are questioning money already, speak to them about BTC.
For everyone else, try to get them to question the money.
