Wait a second... you've missed something.
How about another start: trading is not for everybody. Trading is risky, trading needs learning, trading needs a certain mental discipline (i.e. balls).
If one thinks he has all this, then he can start learning and playing with tiny amounts (and clearly no leverage).
And then the other advises of yours start to make sense.
Yes we all have consent on the fact that crypto trading is not for everyone. Trading is wild fire even experienced traders find it difficult to handle it at times. I always follow and suggest the HODL strategy. Hodl only downside is that it takes times but its less risky as compared to day or short term trading.
