Open Bazaar was announced as groundbreaking killer of eBay and from what I see this platform is almost dead.
And I would like to heard about Bitsquare some more, is there anyone who actually traded there?
Dead? What are you talking about, it has more users than ever.
But yes the adoption is slow because they dont have integrated bitcoin wallet yet which should come out in the next updates.
Both of them need more time to catch on, even bitcoin only had a handful of people in the first weeks, and now it has tens of millions.
The same goes for all inventions!
