Interesting article !

Bookmakers like bet365, betway, willhill are in the 'real' sport betting world considered as joke bookmakers. The margins they take are huge and everyone who understands their system and manages to win gets banned from betting with them. The real money in sports betting is in the asian betting market (pinnacle/SBO/IBC/ISN) who have massive turnovers. All the more serious bettors and big betting syndicates using these. They actually care about the odds. a blockchain that is able to offer 1.98-1.98 odds will get huge.

I'm really looking forward how the betting landscape will change over the years.
