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.
