We've heard this tune before.. Novacoin did this (maybe not 'accidently') and btc-e had to destroy those coins to stop attacks.
Wherever you heard this tune must be drowning out your ability to think (or use google).
NovaCoin did it intentionally, also NVC did not premine for 5 minutes.
They premined 110,000 NVC.
They put that 110,000 NVC into an exchange to try to sell off.
BTB,
ACCIDENTALLY mined 60 BTB for 5 minutes before [ANN].
That 60 BTB, is going towards funding an exchange for the currency.
NOT, 'here is 60 BTB I am so rich now'.
At 1 BTC/BTB that is 60 BTC. 110k NVC, equals 3100 BTC.
But yet people here continue to spread false rumors, lies, false statistics, and their stupidity/ignorance.
It's a goddamn epidemic with how much bullshit is being spread.
