Trading with emotions is one of the biggest enemies a trader can have as emotions draws one into making erratic and less informed decisions.
Emotions easily leads to over-leveraging, over trading, revenge trading, GOMO, and the fear of being wrong.
In cryptocurrency trading, Learning emotional discipline in trading will almost always make a better trader than focusing solely on technical analysis.
Controlling our emotions might be so easy to say but definitely hard to do. We all want good trading outcome of course but sometimes, we can't control our emotions everytime we see the market price continues to decline. It even pushes us to become panic and sell the coins we are hodling even if its really a wrong decision to take. So i suggest the best thing to do is just invest on the amount we can afford to lose so that if we start trading them, we will never be in huge losses if we fall for wrong actions that time. The market is so volatile so expect that it will keep on crashing everytime.
