Claim daily ad spots in a retro marketplace by paying a fixed price before others do.
u/CrispBiscuits · Reddit
I finally shipped my side project with actual payment integration, an retro ad space. There was this outburst on Twitter about outbidding to claim the top spot. I found this concept a bit much and thought, why not let people pay a fixed amount? Then I built this https://www.bidtothe.top/ It's built using AI but designed by me, its not another AI slop. please let me know what you guys think and what i can improve or what more can be done. thanks for checking out submitted by
