Last 2 days I bought for about some cheap coins and it went down for about 5% or something and I decided to sell. And now, I am at full regret that all of those coins are now up for about 20%. My lesson for that is to be patient since the market was down for some day and it will always go back up.
emotions plays big role in trading / even for swing trading .
you should know how to control it , otherwise you will be victim in future too , either of FOMO or panic sale .
