If you mean a version as amazon
Then I think theres a project regarding this, Gemstra project and I guess their ico is stollbkive
It encourages easy and convenient trading on both segments of seller escrow and buyer
Theres a prompt delivery too
There is no need to have an ICO for another project when Forra has a better working product.
Is this a decentralized market and can you tell me the reason why you try to take the amazon as the comparison for this one? I don't even see a lot of review about that.
Remember about so many marketplace icos and then it looks good to hear this one doesn't even require any ico.
