Hi, there. How do I swap my old BlackRose or Koson coins to the new ones? Do you have a way to share with us openly to exchange it?

Regarding the concept of your coin, is it really only used as a means of payment? If this is all you can provide, all coins that have been listed in the market can also be used as a means of payment. Creating a whitepaper for your project is not a bad thing, not all projects only give sweet promises. But among them, there are those who can really make it happen. If you still don't want to make things like that, you can explain how your coins work or the concepts and algorithms that you use are much better than nothing made at all. I don't expect if you only use existing code from a previous project.
