It is really possible to do trading for a living but it is very risky to do it in reality especially in crypto where everything is very volatile. Even experienced traders still prefer having a job that can provide them a stable income than focus solely on trading. If you plan to make it a living, you must have a huge capital separated just for that activity and make sure it can endure some losses so you can still recover it on your next trade execution.
Actually, I really want to say "NOT"
But, I see some people around me and I know several people who are living from crypto trading, being successful, and have some property in the real world because of crypto trading. But, I also know how they are, how they become a success in crypto trading because they really work hard, they are working more than us, taking high risks, lack of sleep moreover at night, professional enough because they will spend their time more to trading activities, doing more research every time, learning again and again. Their effort will really pay them.
But, if we want to keep trading as full-time activity and we don't want to learn much, do more, and also analyze more, it is better to leave. trading activities are not for lazy people. This is hard and very difficult to do and with high risks.
