I have been betting for the last 15+ years mostly living from profit yes. In the past, it was possible to build a lot more volume with bets from other pro or semi-pro bettors. By now, the betting market has sharpened a lot and I mainly stick to my own handicapping and bets to make a profit there. The combination now of Betting/blogging/crypto/trading works quite well for me and I really enjoy it. I'm also able to compound nearly all earnings as I don't have an expensive cost of living along with some passive earnings outside of crypto & betting which cover most of my expenses without having to take on a 'real job' :-)
There is an online movement called FIRE (Financial Independence, Retire Early) which my way of going about things very much relates to.
