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.
This is your fault so that you experience big losses, always use money that is not for important things or daily needs or you can use some of it.
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.
There are many free sources on the Internet that you can use to learn about trading, don't think about doubling your money overnight because this kind of thinking will lead you to pump and dump group that promises big profits, but it's not impossible to lose a lot, because suggesting buying coins low trading volume and only available on small exchanges.
