Completely agree re the api access,an exchange where you havent got it is pretty much an exchange in name only!
The ability to make real time decisions and react to them instantaneously is pretty much the whole user exchange experience in a nutshell for me personally otherwise like you arco and sy id just be using sportsbooks(or an exchange as a glorified one)
I dont think ive acome across anything so far that matches the betfair/matchbook/betdaq exchange user experience in cryptoland.
Yeh, that's the big miss for me.
API access means a whole load of profitable strategies come into play.
Without API access, it's more or less just another sportsbook.
