Ok this post is totally for me - I need to learn how to pretend I'm good at trading for sure haha!!!
In crypto that is, because I am trading in the fiat stock market for almost a decade now. Not that it's that different to be honest, just that I'm new in crypto and I feel like I don't do it right.

About 'professional' traders and predictions, the truth is, even the ones with experience can make mistakes.
When I bought stocks of the Bank of Greece (not some stupid branch of a no-name bank, the national bank of the country for God's sakes...) about 7-8 years ago, before the huge crisis strike, the placements at the time were supposed to be 'safe'....guess what, thousands of euros down the drain...so who's to say and 'predict' really? With what grounds?
It reminds me of the seismologists ... (especially now, after the most recent 6,7 in Greece, they're all on TV as usual...) They say this and that, they do research and bla bla bla and point is? That they just can't predict an earthquake. Same goes with stock market experts, and traders, and brokers I think...

The top10 is pretty funny, but I might follow it - well, I thought I knew and I lost, if I pretend I know I might actually win, right? ;) Cheers @acidyo ;)
