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.
Agreed to your point sell high buy low but can anyone define the levels where is the low and where is the high, no noone can if he/she does not know anything about technical or fundamental analysis, so its important to learn analysis before coming to trading be it forex be it cryptocurrencies, there is nothing different in cyrpto trading, yes currently volume is low in cryptocurrencies so we do not see much fluctuation in price and w/o fluctuation in price, there is no point of trading anything.
