I remember the times i invested some money in this coin and exited when i reach double the profit and that is unfortunate for me, if I only hold my coins until today i have bigger amount of money now in my pocket
Sad story bro
I don't know mate. Our perception of returns can be quite skewed when it comes to crypto. Usually, a 100% return is nothing to laugh at. We just tend to compare to the best returns of the crypto-asset class. If you're trading, however, just stick to a strategy that you're comfortable with. If you flip-flop too often, say between trading and long-term investing, you'll usually end up getting the worst of both worlds.
Remember, you have to hold on to projects that have a good team and good set of achievable goals. Flip tokens or coins that have shitty team or goals otherwise you will regret when they go up x5 or x10 times.
