ok so I just opened the site again to check the odds , and here are screenshots from your site and from betfair
you can clearly see that the odds are way higher on betfair for all the horses , also opened odds checker and found that the odds are higher almost everywhere
https://prnt.sc/jtnvcyhttp://prntscr.com/jtnvzuplease check it yourself and see , the odds aren't competitive at all and I'm sure that I was able to catch better prices before but not sure why it's like this now
there are many people who are willing to bet on horses with bitcoin , but you need to at least be competitive with Fairlay that offers racing but with low liquidity
To explain a few things. Betfair is an exchange which is very different to a bookmaker. I will try and lay it out so that you can understand the difference.
Firstly I will explain betfairs commission structure: Depending on where you are in the world betfair charges between 5% and 10% commission so you have to work this into the price. So if you win $100 then betfair will take between $5 and $10, that means you DONT win $100 you win $95 or $90. So in short the odds you are seeing are not the odds that you receive.
Next is the liquidity. The race that you are showing has the ability for you to have $44 on a 1.72 shot. That is odds to win $31.68 or $30.09 after commissions, or $9 on the second favourite. If you would try to have say $100 on that horse or if many people try to have $10 on that horse you will end up getting odds far below what you are seeing.
I will agree that yes perhaps we were a little wide on the percentage on the race you have quoted, but then I have included screen-grabs from the next at Delaware (race 5) to show that we are in fact offering better odds in this market than betfair.

So in short, yes you may be able to find a race that we are not competitive ( we have more than 200,000 races per year ), there could be many reasons for this. We don't like the market, the conditions are changing mid meeting, there may be jockey changes that we are assessing, there has been a lot of scratchings and we haven't adjusted the margin fast enough or simple human error. But I am sure that we are very competitive in most markets!
I hope this gives you a little more understanding of the way racing pricing works, I hope you enjoy having a bet on the ponies and good luck!
EDIT: I didnt address the fairlay statement you made. Firstly I would like to say that fairlay is a good product and I think that it will succeed in the long run and I commend the guys over at fairlay for the great work that they are doing. But to compare our prices with the current markets offered at fairlay is unfair. I have just taken a screen-grab of the first at presq isle that starts in 30 minutes, there is no comparison.
