Deep regret was not selling anything in 2017. My life could had been completely different at the moment. It has become something that will probably be a life long regret.
I knew that there a possibility that the tokens that I earned will came to nothing someday. I sold almost all of my tokens back then and buy some stuff that I needed and give my parents some money that I earned. My biggest crypto regret is when I sold my tokens at small amount then after a day it gained to much that could be possibly my highest earning. I didn't know that it could be pump that so much and now that token is nothing.
