A possible very serious bug. I placed four bets for Biden on this market (at 50%) and they were accepted as bets AGAINST Biden.

I have been unable to reproduce this bug today. So I was possibly doing a mistake with the UI, but if anyone else ever has an issue like this - please let support know so they can figure it out.

Note: these were limit orders. So I was trying to put them on the order book.

This happenned to be twice today for smaller bets.  There is a SERIOUS BUG.

I think I've posted it twice (maybe three times at the most?). I would greatly appreciate hearing from anyone else that has had this issue.  

Of my current approximately 40 matched orders, 8 of them have had this issue. So I think it is very serious. I've also seen some other issues which make me question whether Fairlay is investing the resources that they should be to fixing their software.  Besides the 17 mbtc that I've bet going the wrong way, it is also very annoying that I have to break up my bets into small test bets to make sure this problem doesn't happen.

As someone considering betting several bitcoin on this website, and as someone who has been in this crypto space since June 2011, I try my best to evaluate the trustworthiness and security of any project where I am placing my funds.  I place more trust in projects that respond in a positive manner to issues and do their best to fix them.

I am surprised that the Fairlay UI (which is how old?) still has bugs in it.  Either the users aren't bothering to report them, there isn't a significant user base, or the company is not interested enough to fix them.  There is a pattern of bugs that I've found (see my post history). So far none of them are serious except for this one where my orders have been switched.

I think Fairlay has the opportunity to be a GREAT website!!!  For instance, there are possibly thousands of traders from PredictIt who are missing the markets that PredictIt cancelled (tweet markets, debate mentions, and others) and who would be interested in expanding into other predictions beyond those carried on PredictIt.  If Fairlay was to be proactive they should be the destination of choice for these traders.  I'd love to see more markets on international elections, world events, US politics, economics, covid, global warming, and more!

If Fairlay isn't proactive then projects like Augur and Polymarket (and others) will takeover the space.  Currently they have all sorts of lack of userfriendliness. They are overly complex and reliant upon liquidity pools, decentralizations, strange tokens, and more.  Also they have limited number of markets, low liquidity, and highly variable fees that discourage new bettors by making it impractical to just bet $20.  However, they are also backed by potentially large software development budgets (I think).

you forgot to add the settlement source of the results

The annoying UI and complicated learning curve has always been an issue with Fairlay, but they have taken us for granted even though many gamblers have reported these issues since they have no competition currently in the crypto betting exchange market.

This could change soon with the launch of Exbet which has a better design and easier learning curve overall. Fairlay needs to seriously reconsider improving their UI.

Exbet is still in its initial stages due to which they aren't providing user created markets just yet, but that might all change in the future once the liquidity on their site improves which seems to be their primary focus currently.

Never heard of such an app. Will definitely check it out. What is its name on playstore?

Even though their approaches are different, both Fairlay and Exbet are regarded as competitors since they both serve the same purpose which is offering Betfair style betting exchanges with crypto as the primary payment method.

Also, I feel that the 1% commission that Exbet charges is pretty low and not a big deal to be honest. I participated in their soft launch and I observed that it has a ton of potential.

Several features like In-play betting etc were missing, but they will probably add them over time.
