Yes, he do. And are you just here to advertise your website? in other's topic?
Nope I didn't Own this Project and I didn't advertise for this Platform I only informed u.
I would be happy if it is my Project...
If you make such accusations you should at least do a little research

.
Let's say John wants to sell his coins, He creates a Shopify store, johnscoinsstore.com lists his coins for sale, sell his coins and he is done.
Let's say Paul purchased some coins from John's Shopify store, Now Paul want to sell his coins, so Paul sets up a Shopify store paulscoinstore.com, lists his coins for sale, and sells his coins back to John or Jane ...
Yes, I understood what you said. But you have not mention how they make a checkout on their own sales website yet. Can John put any form of payment on his website? So who will protect the buyers? If the Paul has sent John money, but John says he has not received it yet, how to protect Paul?
Who is protecting the buyers at the moment at an ICO? Is there usually an escrow?
