YaCoin is different than the other coins because the intial coins were mined by millions of normal people with CPUs.  Thus, there's already a lot of stakeholders.

As soon as YaCoin is able to be mined with GPUs there will be another wave of stake holders.

This is different than any other altcoin so far.

For this reason I think YaCoin will be valued much higher on the exchanges.  Obviously it will go to an exchange.
