I'm sorry for your losses but yes there are people who are doing incredibly well in crypto trading and living all their lives on it. I was once trading (synthetic indices) for some time and my first $2000 was actually from trading synthetic indices and I can also testify that trading though a risky business is still very lucrative.
One thing you have to know is that trading isn't for everyone and you must have to first take things very easy with yourself and try as much as possible to learn the necessary rudiments before jumping into trading and you also have to treat trading as a business and not just merely a get reach quick scheme and hence make fixed plans.
