My worst trade decision was a few months ago. I bought all my investment in BCH and inmediately the market started to decrease. Panic seized me so I decided to sell all.
The next day the market started again to raise.
That's a common theme popping up here. The panic sell is a traders worst enemy (closely followed by the fomo buy). Sadly, ignoring emotion is easier said than done!
Every trader should have a strategy and stick to it, rather than panic. However, sometimes, I would not consider somethings as panic; I would rather call it playing safe. The same BCH has reached my stop loss before, sold it and all of a sudden it started rising back, of course some would want to quickly buy back into it and then all of a sudden it came all the way back down before you know it. That is one controlled market I have told myself never to trade again. So, at the end, it is just what they call moving on, and better safe than sorry.
