Having a real job is better than doing full-time in Crypto. Cryptocurrency is not yet totally accepted in every country so there is a possibility that banning crypto is some other countries are possible and might include our country too. Besides, we can't be sure if we can have a monthly income in crypto alone. Joining bounty campaigns is not reliable all the time since a lot of scam ICO's are coming out. So better find a stable job and take crypto as another way of making money on your idle time.
