i post on forum that i want to buy few coins but no response, also i don't know is there anyone that hasn't throw away coins and didnt lost access to wallet
I still have a few coins, but not much. They are worth nothing at this point. Since Fuse seems like he is done with this, I don't see much possibility of any future development.
Although there are plenty of coins out there that don't have anything special going for them. Some of them are popular just because... Just look at 90% of the alt-coins that have decent market caps.
I think marketing, and acceptance are all that is important.
I'd still like to see KDC survive, even if it is just a plain Scrypt coin with no special features. But I think we need more people to give their opinion. As I said, I'm willing to contribute, but only if we can build some sort of a team effort. Certainly KDC would have more support than most of the coins listed on Cryptopia's current voting page.
