Being a cryptocurrency expert is easy. All you have to do is be skeptic about everything and know that ICOs will end in a burning fireball. It also helps to know a cryptocurrency that isn't in the top 20 cryptocurrencies that is highly undervalued and be able to say why. Bonus: be critical towards Bitcoin, but name the reasons why it controls everything and why it will probably go up again.
Btw, I know all of this. Anyone wanna buy some knowledge? ;)
