Not a big deal ,pinnacles is not the best sportsbook and as bitcoin users we always had large variety of ways to bet with bitcoin, I don't think that i am ever going to use Pinnacle for betting.
On the other hand, I believe that we people should start pushing gambling in decentralized exchanges, such as Fairlay, who offers the ability to bet against other persons for free, so you are actually not paying any house edge to the gambling operator like you do at most of the gambling sites.
Pinnacle account is a must have for every professional sports bettor , there are many events where Pinnacle has the highest odds so if you don't want to use them then you are missing value
but I do agree that it's not that big deal , I was hoping that this may turn other big gambling sites to start accepting bitcoin but so far this isn't happening
if you want pinnacle odds you can have it exactly the same at bitcoinrush , or you can create an account with asianconnect and fund your account with bitcoin
they allow their players to create an account in pinnacle and other bookies
so yeah basically nothing changed , we are able to access pinnacle platform using bitcoin without them directly taking it as a payment method
