I randomly joined the signature campaign yesterday without any real reason or what so ever. But now, i was able to do my proper research and readings about this project and to my surprise, selfpay's beta testing have already begun which is uncommon to ICO's. I'm glad a was able to be a part of this one because there is already a product which, to me, is an element for a successful project.
Exactly, this is one of the very few ICOs with an existing product.
