I come from a country excluded for betfair. I am irritated by betfair brokers, it's not the same. There is no worthy alternative for them. Why has no one built something similar, based e.g. on BTC? Isn't it a profitable business? Is it worth it to ban an account from an allowed country? I have doubts, most of it is probably a scam, and after some time it can be blocked anyway.
Have you taken a look at BTC betting exchanges like Fairlay?
Whilst I agree that Betfair is definitely a great service, it's not the only fish in the ocean.
Take a look at both centralized sportsbooks like Nitrogenbet/Sportsbet.io etc. as well as Fairlay - and I'm pretty certain that there is actually a few decentralized betting markets (that don't have much liquidity within them) hosted on blockchain as well.
definitely agree here. who knows the OP might see other betting exchanges as better than betfair? with his country's exclusion from betfair, he has no choice but look for other sites. with several reputable sportsbooks/casinos here other than btc betting exchange like fairlay, he may find out that some of these casinos can actually serve what he's looking for.
