I keep seeing people complain about liquidity at Fairlay but every time I check it out myself, I can see some pretty big orders there, for sure more than 1 BTC for even the lines I bet,,, I do not think there are that many whales who go for exchanges!
Keep promoting them and they will grow, just like OP says, Betfair took a long time to become popular and that is with fiat which almost everyone could use.
I don't know what liquidity is like there, but the website is a nightmare to look at, let alone use. They have some very odd features and a lot of tech issues historically around bet matching errors. But they seem to be honest and doing their best, and that is to their credit.
I am not looking to 'promote' any product.. If the product is good and provides me with value opportunities, I will be a user.
I am amazed the BTC space doesn't yet have a dedicated betting exchange that is built to professional standards.
I know you are not looking to promote anything, do not worry,,, I did not think that. And I agree that Fairlay website does not really look very friendly, it took me quite a while to understand how to use it, and the fee structure is very confusing if you do not read it properly.
Bet matching errors are common with new platforms just like as Betfair used to face, so that is only natural.
Bitcoin is still tough to understand for technical people, so they are surely doing their best but we just have to be patient. I mean look at even normal exchanges they are still so terrible in general even years after Bitcoin being in existence!
