Hey @kryptocek! Nate from PredictEV (and previously @sportsteem) here. A couple months ago you mentioned being interested in our project, so I'm just reaching out to let you know we launched our public testnet! You can check out our announcement in the post linked to below. If you have any suggestions on how we can improve the platform, feel free to hit me up!
