In any case understanding is the key to success, how can one be successful without thorough understanding? Especially if we talk about trading on crypto, of course the same thing, even I think, every trader should understand more. It is true that crypto trading can change our destiny if we really understand the concept and what should and should not be done. But if there is no understanding, as you said it will invite poverty. Trading is not as easy as turning the palm of the hand, there is a very long process that must be passed for us to truly understand what trading is in its entirety.
The thing to understand is when to buy and when to sell, this comes from experience and if done on paper can yeild the experience without losing money. That and the idea that altcoins will never go as big as Bitcoin should be enough to narrow down a traders outlook towards bitcoin at low price which is the best thing to buy at.
It takes some time to master this but if done with a clear mindset and a bit of faith in Bitcoin it is not difficult. As long as the trader is not getting swayed by shitcoins roaming around or scams running rampant they should profit in the long term.
