You should change your mind now because in Bitcoin trading you cannot increase your assets too fast. The risks of bitcoin are also high, and you will probably lose instead of having short-term profits. I think you should leave and look for a full-time job for yourself because it's right for you.
For now its better to have a full time job because bitcoin trading can't guarantee you that you will take home some profit and of course that profit will also be use for another trade and it can still lose after all. Have a good plan with your financial status, if you think trading can't support your living then better not to focus on trading and do it as your part time job.
I think the same as you because, with a full time job, he can get paid for what he did. He can use some money from his payment to invest in bitcoin or altcoin, he can use the other money to fill his daily needs, and if there is more money left, he can save that money in the bank. That will help him to live better, and he can get more money from his trading.
He can use trading for his living, but he needs to have skills which not all of the trader can have. Besides that, he needs to learn harder than the other traders to improve his skills so he can always make a profit, although it is still tricky. It is better to have two sources of income so he can get more money from that income.
He should know how to manage the risk so he can prevent from the big losses that he might get in trading and he still has money to buy his daily needs monthly.
