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?
Regardless of whether they paid above, below or at market price, they didn't buy to sell.
They bought to acquire coins, most likely for new enterprises which need Bitcoin inventories.
Not everyone is a daytarder. Some here seem to forget that obvious fact.
