There are some people who have been trading for decades, and there are some people who literally do this as a business outside of crypto as well as doing it in crypto. I have a friend who is in finance world, he was in finance world before he met crypto as well and he was earning a decent amount of money, it wasn't insanely high, but it was a pretty decent and a good income, more than double what I am earning right now.

Three years ago he got involved, got a bit of help from me even though not much, and after that he got into crypto and technical analysis and things like that. He got into crypto at around 10k back in the day and had 7 bitcoins, now bitcoin is over 20k and he has over 50 bitcoins. Dude was just good, he didn't became like this by studying after he met with crypto, he was already like this for 2 decades and just used that info on crypto.
