I am not so good in forex trading, but all I know is that many OG in forex has transitioned to crypto trading. Its all basically the same knowledge you apply. For me crypto trading is more profitable and I stick to it.
I would not be so liberal about such statements by some people. Those who have been veterans in one try to remain in that. Mastering one takes time but once its done and is profitable to them, they usually stay in the same. Of course there will be exceptions but this is less common.
And the knowledge is never "basically same". Both have their own nuances and things to keep in mind. So both need practice and a proper mindset to approach.
This high risk also available in cryptocurrency like Future and Margin trading where one can liquidate and loss all money and recovery is not possible. Same as with meme coins and new coins where one can loss big and project can be failed. The only trading is Spot trade which is safe but you should choose top 10 coins if you did not want risk.
Margin and Future are more of gambling without any possibility of recovering the money that you are putting in. It is easy to get attracted to those easy gains but difficult to actually get some profit. Spot on the other hand is the most grounded and basic while being profitable at the same time.
