When I came into crypto I thought I was going to avoid trading because everything was always going up it seemed. I only read stories about the rises in early 2017. Anything but though once I started trading. I looked at the exchanges too often and indeed emotions get to me.
The best way to cope I found is to ignore the price action and simply spend my time figuring out how to earn more. This is different from finacial because we as humans have the opportunity to find ways of earning more crypto which in turn more $$$$. Crypto can drop 50% but if I could double my quantity of coins/tokens by mining or partaking in giveaways at the end I am still earning. When the coin does moon I would be in position to gain a lot more.
So yes I worry when markets crash but I do not cash out because I am too involved to getting more coins to compensate ;)
