Back in June 2017 I had my largest earning month of my life - cashed out $70,000+ and lived on it for the rest of the year while trading. If I had left that in bitcoin it would have been over $500,000 by December. And worse, I was a huge bagholder in MAIDsafe coin and eventually took my biggest loss... a great study in hindsight but I sure don't like losing over 10k on one trade.
Even with my string of mistakes, I am way in the profits because the things I did correctly made me more money than my mistakes cost me.
