Here's my wild thought: Why don't create a new Cryptocoin : XCoin2. Pure PoW? No premine. Limited coins ( 1/1000 as per Coin2 ) total of 80k - 100k coins? Employ same X11 combine with ???whichever??? Algo tech with advantages.
There you've got an instant 8 digits Santoshi Coin2
The new XC2 will share mining operation with coin2 staking power.
Not sure that doable though.
XC2 then will listed in exchanges separately, outsource mining pools.
Then Coin2.1 will release an upgrade wallet allow inter-exchange XC2 and C2.1 at market value with fees.
All profit from service will go to Coin2 foundation as reward for future developments and payout for Board committees and Devs, annually/quarterly...etc. Incentive on hardworks, volunteers not, always has a positive returns.
