I have friends who quit their job and became a full time trader.
You can do many things if you're going all in.
You can open up a business about cryptocurrencies, not just bitcoin.
My friends opened up a Educational Website where they teach people how to trade and they are getting paid in BTC, another one of my friend posts signals for trading where in he too is getting paid in BTC.
It's really up to you. Have a great day, and good luck.
