Odd Even Betting

Hello - first time posting here. What is your opinion about the viability of a gambling site focused entirely on the concept of Odd vs Even betting? I see there is Odd|Even betting in sports gambling where you can bet on Odd vs Even goals in a football match or other sports. There is Odd vs Even betting (and random number generation Odd vs Even) in roulette. And there is the emerging crypto-blockchain phenomenon where gamers can bet crypto currency on the Odd or Even outcome of the next hash or block code.
I am asking because I have several OddEven domain names (one of which is in use in the sustainability sphere) but a few others such as OddEven.bet that I am considering putting to work. Is there suffiecient market for a single site that could satisfy those who would gamble on 3-in-1 Odd|Even: sports results, on random number (0 vs 1) generation for roulette, or blockchain crypto? Gaming appears highly regulated so maybe an affiliate is the only viable option. Expertise of members here gratefully accepted.

Welcome aboard,
I would think there is a market that you could make work although I do not know if it would be profitable or not.

Best thing to do is take one of your names you think to be brandable and start putting your ideas to work. Test...test...test...

Posing the question the way you did will likely gain you some suggestions and possibly some caveats to avoind.
