Or you can earn your salary in bitcoin, change to fiat if you need to. Or find solutions which allow you to stay within the bitcoin ecosystem
I recommend this too to catch up with the non-stop increase of bitcoin for this years that will come. Convert your money to bitcoin as long as you can since this will make you rich if you decided to bag all your money and make it bitcoin.
Well there are certain measurements that people are considering before they are going to convert there money into bitcoin. And for me it is risky if you are going to work full time with bitcoin and going to leave your full time real job. But if you are not going to leave your full time real job and still going to work for bitcoin well that's good.
Earning from both of them is the right thing to do, as full time job will take care of you and your family and bitcoin will take care of future investments.
