I did the same 3 years ago and I have no regret of any kind. In fact, I am making my monthly payment just within 3-4 days and in the worse case scenarios, a week maximum.
It means that you are an expert in trading, you have a good attitude and a passion for the job and that allows you to make a profit with full-time trading but if someone follows you, I cannot guarantee that they will have similar success. In the world there are many famous people and they give up learning very early, many others refer and follow, the results are not as expected, trading is not a world that can create successful people, before giving up full-time jobs, we should also experiment for a few months, not to lose more to a hasty decision
That's the problem, there are people who are great at trading and they could make a lot of money, I have a friend who used to make about 5k dollars per month as salary, now he is so rich from crypto trading (he has been trading for about 3.5 years, a bit before 2017 peak, spring of 2017 if I am not wrong) he is making about 25k dollars PER DAY, on average of course but he has about 5 million dollars and he doesn't trade most of them, he just holds most of them and trades other stuff and all those increases comes to 25k per day, that of course because the bitcoins he hold, the bnb he holds, the eth he holds all goes up, I am including them into this as well, so 25k profit per day on 5 million dollars is still a lot but when it is all purely in crypto during a bull run, it is quite possible.
I have been involved in crypto far before him, 5 years before him, and I have 7k dollars total lol. So, some people are great at it, and some people are not, just because one made a profit and became a full time trader with no problem, doesn't mean that others can try and do the same.
