I really doubt this is a scam because AM/FC has shown integrity matters more than profit time and time again (200 btc fee returned, prisma refunds, etc) , however the lack of professionalism cannot be ignored. Even if they do somehow make it out of this mess, I hope FC steps down and replaces himself with someone more qualified.
My view over this. There was no other option to the 200 BTC fee except to return them. I can only imagine the investors going crazy if this wasn't returned. As for the prisma refunds the amount doesn't seem too big to me. The batch and the refund weren't that big to really hurt AM. Considering this these 2 points don't really support AM THAT much, but don't get me wrong. These 2 acts of kindness must be appreciated and respected, but not to that extent to bet all the money on it.
Why would FC even waste his time with Prisma refunds if he was going to pull a fast one only 2 months later? And why would he halt AMhash sales?
