There are no market instruments that are 100% the same, they could only be similar, and this is because of the sector differences, there is no way the economics of Forex can be 100% similar to that of Crypto because they are not the same asset class. That is why you might see some economic news that was so significant in effect with Forex but had a minimal effect on Cryptocurrency. The characteristics of the asset class also explain why Bitcoin, for example, is mostly sluggish in movement than volatile, and this could be so discouraging as it also causes me to avoid it for Forex trading many times.
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?
However, I've never totally abandoned one for the other, I trade them both weekly, yet, I trade Forex more because it gives me more trading opportunities and earns easier for me when Bitcoin which is my preferred crypto would take a longer time to bless my trading account.
