No crypto trader needs to learn anything from others, Crypto has it's own rules when it comes to trading, It's called buy low and sell high, That is what happening all the time in crypto, We have these insane fluctuations in price and that is the only thing one should be aware of when it comes to trading cryptocurrencies and especially bitcoin in particular. Most important part is that crypto market is not really protected by any laws, Only the laws of decentralization applies here.
The thing with crypto and Forex is that they are two different market, different conditions, different fundamentals, but same technicalities when it comes to the market. Although, we also have to understand that the cryptocurrency market is very volatile, which is one of the reasons you need to understand a lot of things about the market first, before even making any serious step.
Following Forex traders is not a must, personally for me, all I did was to learn as much as I can, and it was even cryptocurrency that led me into learning how to trade, and it was after then that I even started going for stocks. So in a way, you really do not need to follow a Forex trader before you learn how to trade.
