I'm not sure the site would be a success, even if I did create dark mode, etc.
The game is too risky and the trust required is too high.
So it looks like it's time to end this project.
I will wait for the existing auctions to end and then take the site offline.
Thank you everybody for your feedback.
Too bad the project ended like this, I mean, it was looking nice and had potential, but as you say the trust required is too high, and for that you need a lot of operation time, at least one year up. That's the right way to build trust.
If there could be a way to avoid the risk of the users about the house running away with the money, then people would easily trust the project.
