I contacted with Nrigo, gladly I did.
Originally I am going to propose to Coin2 moves to next stage after all these years hard work with many existing games being implemented with coin2 and gone un-notice by the crypto communities at large. The idea is to change the algo or create a version of mother token with Bitcoincash Cash fork then convert all the existing Coin2 as GAS continue to use in gaming but will be delisted in exchanges. Coin2 will be automatically swap to new coin back and flow. The new Bitcoin Cash fork Coin2  will be airdrop to Bitcoin Cash holder 10 to 1 and Coin 2 holder will be 10 to 1, remaining will go to assist Coin 2 further focus in the area. I even try contact an ICO exchange for the concept.

However, I find out Nrigo have done even better Job. After all these times keep silence and let Coin2 team  pursuit their area of interest, seems pay off. I am very excited.

I still hold  2 wallets each with the 1+mil of C2 untouched for more than couple yr.  I recall one of the wallet used to be at 13th place in richest list.  
hope you guys continue the good work. If necessary, I will donate 10% of my holding to Coin2 where funds needed during swap and 5% toward the faucet again as I did in the past.

Cheer.
Happy New Year.  

Novaexchange is closing soon, and people storing C2 on it might not withdraw before it closes.

Is there a way to find out which addresses belong to Novaexchange and exclude them from the swap?
