the fact we dont know the price of AMP at sale in Septmeber is brutal, market will jump or crash, it is like betting in box, you may favour one guy, but he still might be KOed anytime.
I thought the purpose of another AMP sale was to bring in new investors. So the lower the price the better?
Sure but not for people that are buying now at all time high prices

I mean if there is possibility that AMP will be sold at lower price that in this moment at exchange, you should wait. I personally have account on Banktothefuture and invested there in factom already.
