I still don't understand why you people keep calling it an exchange when you cannot even lay bets. It's just a decentralised sportsbook with players deciding the odds plain and simple.

It's similar to sites like Polymarket where you cannot parlay bets either and is totally different from proper exchanges like Betfair etc.

You can only place lay bets by using the API or any custom interface. From experience it is not advisable to allow regular users to place open orders.  They will get matched at unfavorable prices or other users take these orders when the market is already in-play  causing a lot of disputes.

But nowadays with all these AI-Tools at hand it's very easy to write your own python script  or Javascript app that runs in your browser.   https://github.com/Bitcoin-Betting-Official/Bitcoin-Betting-Javascript

This is just a proof of concept, but should work:  https://ipfs.io/ipfs/bafkreig23znqnsff2zcjbmgpiu4jews3zpj7asg72aorn6dtycgjsfhhzm

There were some other requests in the past for a tool, that lets you place a bet on a certain market with a certain description and title  whenever the odds are above a certain level.  If there is some demand for it, we can implement it.
