there will be no effect, since they can't dump something purchased for 30% more, unless they are stupid, also i don't think they want to crush the price, therefore in the case of a dump, it will be done outside of the market
Why would they purchase something for 30% more if at all they want to dispose it?
All we know is that at the bitcoins sold at least for greater than 17% less than market price, so at LEAST $224. But no where was it said that the buyers paid more than 30% market price!
