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

The rumor was started by a tweet from a twitter account called cryptokees. It's based on nothing but his claim that an "anonymous source" told him before the winners had even been notified. His corresponding bitcointalk account was tweeting for free giveaways of low value plankton shit coins last summer so he can't be rich.

He mentions a coindesk article in his tweet, but there is nothing about 30% above market price in it. I think he just added the coindesk article link to con people into believing it backs his rumor up, which it does not.
