If you're still looking for sportsbooks that accept BTC, I'd recommend you to check out the Bookmaker's Review site, they have a rating guide with the top betting sites on the market and you can check which of those sites or online sportsbooks accept crypto. I think they also have a list with just crypto books. It's really worthy to check out, it has worked for me a lot in the past couple of years.
