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.
I think that it is a lot harder than you think to set up a gambling platform.
All the regulations etc. make it a complete headache.
So no, there isn't a 1:1 copy of Betfair that is available but you can get close to that if you use something like fairlay? But of course nowhere near the liquidity of Betfair.
