Day trading isn't for everyone.If cryptocurrency trading isn't for you,leaving this "business" might be your best bet.Some people are created for a 9/5 job,while others want the risk,the excitement and insecurity of day trading.
Happiness is just a concept.The journey is more important than the goal.
The meaning of life is to keep grinding and never surrender.Maybe you will find your purpose some day.
Good luck,OP.
It depends upon personal experience if anyone want to do trading as a part-time work, full time work or quit his job in order to give dedicated time to the trading.
In my opinion you should not leave your 9 to 5 job as you can keep trading part time and also while on job. Day trading may not be an ideal thing to do if you are busy with other things as it demand dedication. However swing trading can be an ideal choice for job holders.
