Selling on that website?
There's even nothing there, literally like nothing and an annoying popping metamask window, don't tell me you need to log in metamask every time the site is visited?
Yes if you have any private deal that requests a public escrow, it is a good platform to complete it. It has no centralized database and the platform is sticking on Ethereum, a very very strong decentralized network, unlike ordinary deep web market like Dream / AlphaBay, it NEVER GONE!
yep the trade off is like you having to install some plugin to get access to Ethereum network. Metamask is extremely user-friendly and it won't cost so much time comparing with using Tor connection and trying many unknown mirrors. If you have experience in it, you will get this mate!
