Hi there!
There so many different blockchain project that were starting to be confused..Id like to ask whats the unique feature of yours?

They want to create a global marketplace, like Aliexpress, but for crypto-users

That's a good idea, a project for everyone around the world using cryptocurrencies.

Yes, but it is also a very tough market. They will compete with ebay alibaba amazon and etc.

I really wonder how will they perform.

Idea sounds good and useful. The competition should't be that tough unless big companies as you say (ebay, amazon, aliexpress,...) get into crypto.
