I got into altcoin trading just recently, a week or so ago.
Honestly I never dealt with exchanges before and this is all new to me but it's both fun and very stressful. I'm not a big time player, in fact I started out with nothing and just mined some Hush, sold that and bought ARK/Waves/Shift/Espers. I own maybe $500 worth of coins right now lol, but I plan to increase this.
However stress is getting to me. I keep checking the prices, trying to buy low and sell high and I do that at work now as well and even dream about it. I dreamed Espers was getting pumped and my exchange closed Espers trading and I woke up all pissed off and sweaty and cursing the non existent exchange.
I'm not very interested in the tehnology I just want to trade as I find that a lot of fun. But I need to deal with the stress somehow

You are just getting too serious with this stuff. If you are really enjoying on trading you should not think it too much inspite on stressing out yourself its much better to follow the essential steps on doing trading. Buy low sell high just like that. Stress would be more if you do see that all of your coins are on negative which if its your first time you would really panic and cut loss for sure and you should really be ready on this one because it does give more stress than on the thing you are experiencing as of now.
