Obviously it's not for everybody, just like having a job or a business, you only do it based on your skills and passion, without that in you, you'll never be effective in the field you are trying to pursue. Trading is very risky, you are investing in yourself here, so you also have to ensure that you understands what you are doing and you believe that you have the skills to be successful.
Trading is more of your luck then how much knowledge you have and how proficient you are in using trading tools. One thing we need to admit is that majority of traders end up losing money that's why its called trading is not for everyone. One more thing about crypto trading is that its fundamentals are still very immature compared to stock and commodity trading. That's why I say its more about your luck.
I think I agree on that, trading is a good way to earn in crypto but it is hard to do trading specially on a high volatility market that always change, so even if you are a knowledgeable trader there are still big possibility of loosing, because the market always change time after time that is why sometimes I believe that trading is not for everybody because not all trader has a luck on trading many people also loss on it.
