I have few question regarding this project:
They have only centrally control wallet and market, how it will add to other exchanger or services?
How it will grow, if other 3rd party services can not use it without invitation?
How exactly invitation created?
Small addition to awesome KAMO response about centralized wallets - actually there is also full node wallet, not only centralized. You can run full node for yourself.
