There are also many stories of people who have suffered a lot by trading Bitcoin. You too can get hurt by trading in Bitcoin in the future. So you can do a job or business first, as well as Bitcoin trading, rather than building your career in Bitcoin.
Everything we do today as far as our earnings in the crypto space, I don’t think we are 100% sure that it will last forever, but rather we use it for a main purpose or we use it to create another way of earning money outside the crypto space, such as physical business or something similar to that, so that anytime we experience losses or bad times here, we can confidently go back there without suffering from financial problems.
I will also like to add on to what you have told the OP. Business is very important. Most people I know use the money they get from crypto to create businesses, so if the OP also does that, it will be helpful for him. Rather than just depending on trading bitcoin, people lose and most normally don't get their money back because the more you trade, the more you will gain profit. Sometimes you will lose, so, OP, don't build your career trading bitcoin; find another way of earning.
