It is not wise to leave your full time job just for trading crypto. As of now it is not stable and unpredictable. Maybe investing needs time but you should not sacrifice your job for it. Its better to keep your job, earn some money, fill in your financial needs and invest your extra money on it.
It is just a matter of taking risk and how well you are going to do bitcoin and other cryptocurrency, I do have a lot of friends doing full time here and never regret of leaving their job, that makes me confused as well if I am gonna continue my study or just focus here, well it is my accomplishment if I can do both.
Risk is good, but it is always better when calculated. I am sure since the OP has been in the employment world, he should have been able to consider that fact before making his decision. I am also sure he must have been able to learn trading pretty well to have been able to go ahead with that decision. Trading is a job on its own which can be highly profitable if you have the cash and you give it most of your time and do it very well.
From my personal experience, if you have the money to start trading and you have the knowledge to go ahead with some little experience you must have gained, then why not ?
Trading can give you a whole lot than what any job can ever give you if you are good at it and you doing your best. Put those time in it that you would give to normal job and you always be swimming in cash. You will even have the chance to dictate your own time.
