The more I learn I am kind of coming to conclusion that trading in the long run is not profitable.
How are you drawing such a conclusion?
I mean I don't know any single person who is doing decent amount of money for living by trading in crypto.
This depends upon your perspective, if you are thinking that you can leave your job and get into earning millions by trading then you are wrong. Again it is also true that you can make a certain amount in trading that might vary every month and be happy with that while running a job.
In other words - Trading can be a side hustle for many of the users who know the basics of stock market trading and speculative markets. It may not be enough to support your living.
Hence the question: do you know anyone who is successful trading in crypto? or are you doing well by trading crypto?
There are professional traders, but dont hope to become one yourself. I follow the simple method of buying low and selling high - this takes time to cycle over the bull/bear cycle but churns out decent profits if you have patience.
Note: I am talking mostly in terms of long term Spot trading.
