Do you bet player props or props in general?
Having luck and making money or is it more of a fun thing?
I rarely do, because it's even more time-consuming than just analyzing the ML/HC/totals markets and you even need some more in-depth knowledge, have to look for some "insider" information and last but not least have to understand the game way better. If you are willing to put in the work, then you can find loads of value in these markets, but you won't be able to stake a lot in general, because bookies know they tend to give away value (more value than they normally like) by offering these markets.
I do know a punter who specializes in NFL player props and he is doing really good, with a huge yield for NFL standards.
My Sportsbook right now is stake.com, could any of you recommend a book that has a good selection of props for NFL Games?
You will have a hard time finding a lot in crypto books, as you already witnessed. Bet365 is the go-to place for traditional bookmakers for these bets and as a fiat-crypto-hybrid bookmaker I would recommend to take a look at betonline.ag.
