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.
That's good advice but easier said than done - who among us hasn't felt the overwhelming urge to panic sell when their coin starts to tank? Nowadays, I just invest in projects I believe in and forget about it for a while (although I check CoinMarketCap more than I should! LOL)
