I have been in crypto for quite a while. I used to think of leaving this industry for several times already way back when the trading was greatly affected by the bitcoin dive. But when I learned to trade in the declining market rather than waiting for the prices to go green, I make it a regular habit to make an earning out of it. Even when the profit slows I don't think I would quit totally for now. There are many new opportunities that comes along, like ICO's, or coins that after careful research would be considered promising and profitable, most of the time through trading and not for hodling.
