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
of course I and you will do the conversion or change your income from bitcoin to fiat. due to this moment you know that bitcoin is not appropriate to be major currencies. to be a job I think bitcoin still suitable but for living in bitcoin. I'm not sure of that
but if you already earning a couple of bitcoin in a daily basis becasue on what you are just example trading or offering services i think that earnings is enough to quit and focus with bitcoin and that is not impossible if you looks on the trading site many many whales and investors are their now putting their time because they know that they found their bread and butter.
We should quit our job if we see that we are earning more in the crypto world base on the time spent against the time spent in real job. I know in Asia they work 8 hours a day and will receive a fix rate like $10 for 8 hours of work but that is so manageable that we can get by working online.
