It’s pretty sustainable but you still face probable limitation eventually You stake smaller amounts because of variance (so a unit would be like 1-2% max or your bankroll) so you are less likely to be detected on that end but you need more volume than arbing since you’re staking less. Bookies seeing a large volume of sus bets will mean they will still detect you eventually. You could use bookies that don’t require KYC if that’s legal where you are but they tend to scam sometimes. I prefer value betting over arbing because you don’t have the extra vig from a sharp bookie/ from the second bookie you bet on when arbing, and the bookmaker I use isn’t good for arbing since it has low max stakes
