3) What are the coin totals for the new coin and snapshot ratios for Cinni 1.0 and PTS/AGS?
Cinni's total coins about 15 million, 1.5 million for Bitshares PTS and 1.5 million for Bitshares AGS
so about 18 million total coins.
1.5/18 is less than 10%, then you may violate the social contract. Alternatively, you can allocate 18.75mil coins and distribute 1.875 cinni for PTS and AGS.
