I'm sick of the fees on Ebay it's become totally unprofitable for some items due to the massive fees. I use Facebook marketplace but that's more for local sales.

With crypto Ebay you could have near zero fees and have a decentralized marketplace model. I know there are things on TOR etc, but I just wouldn't trust it tbh. I can imagine Amazon buying this project one day for more than a billion $ as it would feel 'threatened' by the merely existence of this model and will end up incorporating it into their own business model.

I mean EarnBet (https://earnbet.io) an online decentralised casino has been the latest to solve the problem of wagering via crypto and is operating on the WAX chain currently.
