I have a question... do you think it's a good idea to invest BTC in futures now? With 3x leverage so as not to run as much liquidation risk?
If bitcoin is at $60000 and you long it with 3x, the liquidation would be around $40000. If you can take the risk, you can go for it.
Waa, this is risky enough, for me, I am not taking this high risk. But not really sure with the OP.
In fact, if the OP wants to utilize or optimize his €100, why should he choose to do it in Future trading? Isn't it true that with this, the risk of losing it could be higher? Indeed, maybe you will also get high profits, but if you don't understand the tactics, this will actually endanger your money.
So, wouldn't it be better if you wanted to save that €100, it would be better if you bought Bitcoin and held the BTC until at least the next bullish era? Is not it?
