This is got to be the strangest coin sale I have seen.
You do not have any backing of your coin or any route of how you plan to handle something as it comes along.
Is this the proper way to operate your coin?
I don't know.

Well, I think that it is unfair when dev keeps some coins to himself. Users buy my coin and if price will grow - this will happen thanks to the users. Users give me ETH, why should I also keep any SPC? What about plans... As it was mentioned - this coin is about trading, not about features and technologies. What plans does it need, excepting listing on some exchange?
