This question seems so simple, yet the answer seems to escape me. Both involve technical and fundamental analysis, which includes indicators, charts, and candlesticks. They make use of the same trading principles, ideologies, and strategies. However, I have yet to see a forex trader who has dumped forex trading for crypto trading. I have yet to see a forex trader who doesn't claim that they make more money than crypto traders. I have also yet to see a crypto trader who has dumped it for forex trading. Have you made a move from Forex trading to crypto trading or crypto to Forex? What happened? Can one do both at the same time?
I have a friend who move from stock trading to crypto trading since stock is a little bit slow to get profit compared to crypto then he decide to move all his money from stock to cryptocurrency. Both of them are the same just like you said they use analysis, charts, etc. The main difference is probably the volatility and the risk that both have.
