If there's a project that has a lot of potential, then I will.
Rather than quitting in my real job that pays me a decent salary, I will make my bitcoin earnings as a full time job during my day off. Extra income with a blast.
Remember, day offs are there to rest the body. Your body needs to recharge too. If you keep on working without resting, you will be stressed out in no time. I recommend, take one as a full time and take the other as a part time only. It does not matter if bitcoin is full or part time, as long as there is still enough time for rest and your earning enough to make a decent living.
