Any confirmed coins from those 8? I think one of them is aspect coin. It is x11 too and after mn sales,  old  dev left the project.

By the way your swap ratio is not fair. There is no difference between to holding one coin or 5000 coin. If you have money you can buy 5000 but if you don't have you can not more. But it doesn't mean small holders not believe to project as they purchased coins... I think, people who bought mn on auction tought they deserves more coins. Imagine you have 900 coins and after the swap you have 450, does it sounds fair to you?
