1) Too much stress.
Yes, I believe you understand me. My mood depended on one or another token value. I couldn't work sleep and eat. I was checking value for 15-20 times per day. I could not live like that any more.
if you really don't have a passion in trading, then your activities in trading certainly will never make you happy, even make you depressed. the market is fluctuating, and difficult conditions in the market might be stressful, because you're not ready for that condition, if you think so, it must be stop to trade.
