Getting rich in crypto is possible but not quickly, if your lucky and find coins outside the top 100 with a good team, the coin has a use and isnt just a copy of other coins already available then its more than possible. However any coin that has guaranteed returns should be avoided at all costs. Bitconnect being the example, although anyone caught up in the bitconnect scam was blinded by greed and shouldve taken the time to thin about here the 'profit' was going to come from.
