Of course, in everything we do, we have to learn it first, as well as in trading, there are many things that need to be learned before doing it, but what you have to remember is that crypto trading has a very big risk, even though it's worth it with the possibilities, it's not a solution.
Both trading and investment requires serious learning. That's why the beginners shouldn't' hurry to spend money for crypto coins.
Learning becomes more important in crypto because it has a high risk and unpredictable. People with lack knowledge will have a big chance to lose money, it is because they probably feel panic and take a decision without good understanding about the problem/case.
for people who are in economic difficulties, trading makes it possible to further exacerbate the situation.
Do you mean people who has a problem with financial, he/she doesn't deserve to trade crypto?
I think everyone can trade crypto as long as he/she has good knowledge and use the amount of money they afford to lose. Trading shouldn't exacerbate the problem of financial if someone can trade properly. But surely that we can't rely on trading to solve the financial problem. There should be more efforts to have other jobs. Trading can't guarantee to give regular/constant profits daily. So, we still need other jobs that can offer regular income.
