Good, now all they need to do is liquidate all the fake money for real money. Pull the real money out of those that holding on to it after selling the lemmings fake money and let the system implode on itself.
How does one seize a virtual Currency? Do they transfer it to another wallet they only have control of? Otherwise if multiple wallets/backups exist, the wallet owner could still remove the funds and in that case they are not seized. Digital currency can't be frozen or contained unless you are sure you have the only keys to it, or move it to a secure wallet. Not enough details in this to really understand what they have or whether they have even secured it (Transferred to a secure wallet).
