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.
trading in any finance market basicly have same system. technical analisys will stay same in how we identify market . alot forex traders also trade cryptocurrency because they see there is no difference with fx. for which one is profitable it depend on our skill analizing chart and price.
