Here's my view: If volume jumps up that much it's mostly traders from what I've observed. It should go down again, everything else would be very weird. The pumper(s) have just waited for the vaults from home, that was the next big news from Maidsafe. They have accumulated MAID shortly before dev updates and sold when no big news came. That's what I think I have observed at least twice. So now theyre pumping it up a lot, ppl fomo and jump in, just to be surprised by the sudden dump.
FWIW, I think it won't go down that much anymore, at least a couple 100 btc will probably stay.
