Okay this make sense now.
So roughly, 1,289 bitcoin is in the wallet which is totally crazy. Though, it's too early for now to speculate about sudden pump.
Or could this be just hyping?
Possibly tho, because some people tend to believe that there will be a good move coming if some "whales" are transferring huge amounts of bitcoin that there must be something that will happen in just few weeks. Or this is just a decoy or just some normal balance movement from bitstamp itself.
