The money is most likely coming from other people doing the same thing.
or from the newbies you sucker into buying your shares...
remember this:
Anyone with an attention span greater than a gold fish knows what he's talking about. 50 Th/s coming online in October. Why does that worry you?
or this:
They've stated that they plan on bringing 500 Th/s online by the end of the year. That is a valid possibility. If they did and they controlled 5% of the network, then the network hash rate would be 10 Ph/s. I think it's more likely that Labcoin will have 500 Th/s online than the network will be at 10 Ph/s by the end of the year. If the network was at 5 Ph/s then LC would need 250 Th/s.
those quotes were not very long ago...
