Personally I don't know any full time traders, I only hear about their stories of success, what is hard to measure how legit they are, because anyone can speak anything about themselves, especially on the internet.
I believe if the person has fixed sources of income guaranteed every month, he can become a full time trader, as losing money isn't going to be an issue for him, but if the goal is to live solely from trading activity, that is a huge mistake, unless the person enjoys living on a tightrope.
You could barely see them because they arent posting or letting themselves known publicly and decided to be silent on what they are doing and only a few would really be boasting up that they are a full time trader.
But for sure they do exist and there are people who do really able to sustain this market which is something that is hard to attain or reached by someone.The ones who do able to make out some sustaining
trades for long term are the ones who are really doing well which is profitable honestly which you could really make this as a main source or full time job.
Well, I don't personally know people who work and live from trading, but I have a friend who goes to visit and she told me that she had a couple of friends who both are dedicated to trading and apart from that they live from it, of course they take advantage of everything which is fashionable, as in its time NFT games and many of their service payment accounts are made by esps games and the other is dedicated to mining.
Mining and trading is what they practice the most and so far they are very profitable, I don't know what methods they apply or how they do it, but it really works for them.
