Today Stellar showed everyone his strength) I think the team ZED has many reasons for this choice.
yes Stellar blockchain is very promising. I see that more and more projects use it as their base. And ZED is one of them.
Yes you are right with that and with the partnership of Zed network and Stellar there are more projects to come in the future and more amazing services both of the team will provide to all of us and that is one of the big reason why the success of this ICO is for sure.
Zed Network is not the only company which partners with Stellar. I know some other perspective ICOs which prefer to use Stellar blockchain. Good for everyone.
