Hmm, I never had the option til two days ago even though my wallet had always been connected. Something still seems off though. It's showing that the coins from Metamask that I bet are now "locked," but they are also still available in my wallet to trade etc. Surely it can't be both? Also I don't appear to be earning more per bet from what I used to bet, despite increasing my bet size by over 10x or 15x in many cases.
