So I'm about to invest in cryptos for about 1500 euro after trying it out in september with great failure, lost a bunch, bought high and sold low cause I needed the money. Now actually I'm thinking of flipping coins, find good coins in dip and sell them in pump and repeat in other coins, I'm gonna stop cashing out cryptos in need of money.
You used to trade on emotions and it was a terrible mistake. You need to be disciplined and make up your own strategy to become successful. It will be great if you manage to find good coins on lows and wait until pump, but actually, not always even good coins go up, so you need to be patient and know when to sell off so as to fix profit or at least not to lose too much.
No, he didn't trade on emotions. He traded out of necessity, which is even worse to begin with. If you don't give yourself a sufficiently long time horizon for your investments to perform, you get stuck in exactly the situation you found yourself in and you got to sell out of necessity.
Even though crypto is extremely fast and volatile, be somewhat realistic about your expectations. If you hope for a coin to double within a week but instead it drops by 20% and you have to sell, that's just your fault. Take money that you can indeed just leave where it is for a very good while. That's how you can swallow short-term decreases in price and be patient for the pump that you expect based on your analysis.
