I would set the minimum bid on Flippa far lower than the $125,000 asking price if you want to get any interest on there. People on Flippa are not startup guys and are a lot more realistic about valuation. I for one would be interested in exploring buying this, but it's not worth anywhere near what you're asking, so it's a non starter for me.
Two separate points there. On Flippa, you want to start lower to generate interest and start bidding, but you want the bidding to build up to a higher amount. But it's also true that Flippa users tend to be "value investors" not ones who buy high potential. They also are not developers.
