Today, traders in stocks or forex are mostly traders among them who are switching to crypto or bitcoin and holding bitcoin and top altcoins because of the bull run that is coming. That is the truth.
There are legit traders who focus on one market and dont move to others recklessly and then there are showoff traders who talk big and dip their hands into non-crypto trading and eventually bring their burnt out faces back to crypto.
Indeed, no one speculative market trading is superior, all have their own pros and cons. But if one person is well versed in a certain type of market, they should keep themselves limited to that one only. However getting a fixed or close to fixed amount every day or month is near impossible because trading is not like a job that pays you a fixed salary. Sometimes you get a good profit sometimes you dont and hence the mindset should be like that only.
I believe that one should always keep learning something new but one should not experiment on anything without learning. I agree with you that trading is not like a job in which one gets a fixed income. I know a lot of people who make a lot of profit in day trading because they have mastery over their work and their market research is huge. They have learned very well when to invest, in which coins, and when to close our trades.
Trading is not a child's play in which anyone can experiment and become successful. I can say that if we understand the market well, we can benefit a lot from it, but this can only be possible if we work hard ourselves, do our research, and do not follow what everyone else says.
