What can make sellers leave Amazon and start selling their products on the PHORE marketplace?
I think it will be very problematic.
Sellers can place their products for free in the PHORE marketplace.
As orders from the PHORE marketplace grow, sellers will be able to abandon Amazon and other services.
I like that all transactions between the seller and the buyer go through a smart contract and do not depend on a third party. This is an advantage of the PHORE project.
