Swap proportion will be 3:1 from ERC to ERCv2.
This means that if you have 3Millions ERC you will have 1 Million ERCv2.
Total coin of ERC v2 will be around 90M , starting with 31M circa of swapped coins and with Total Coin Generation estimated on 10 years from now.
Whatever you do please! Don't change the name of this coin, adding suffix will make the coin harder to market; in short, that will backfire on us. And believe me branding is important.
BTW,
What is the total of coins available right now?
