Hidden premine?

This should be interesting

is this going to be the one that switches algos randomly and requires a special miner package???
i thought roulettecoin was it, and they were still busy premining it, but maybe there's a special trick up the sleeve yet.

To bad it is SHA, it could be a X11 and still bring in "ASICS"...

Rolling back to 7408. All vulnerabilities have been closed. Coin now has no flaws. I will post a detailed response on what happened, why it happened, and how it was so easy to do. Thanks to earlz for finding the mystery and MrData for his help with the rollback
This coin has a mystery...
It's not malicious...
It's not obvious...
Virtually insignificant...
But when found...
Will raise the due diligence standard
Third party pools. We take no responsibility for down time or lost shares. Contact Pool Operator for support
Please post your pool picture and link to be readded once you are updated to the rollback
Pool operators will probably have to run the daemon with -disablesafemode for a while until there enough new good blocks to be a longer chain than the old one
Pool Operators: Your pool will be listed once you post a confirmation that you have updated
