Do you think you can win the competition with Amazon and Ebay?
I think that it will be very difficult for you and users will not want to switch to a new marketplace.
Amazon and Ebay are market leaders.
I think that the transition to the PHORE marketplace will be a long one, but in the end everyone will switch to a new marketplace.
In my opinion, rivalry with Amazon is hopeless.
The PHORE marketplace should find its community and grow towards specialized sales.
I think you are mistaken. People will choose a more economical option.
