I always keep seeing some apparition buy walls that keep appearing and disappearing on cryptsy and mintpal. If that's any indication, it's that DARK coin has investors waiting in the wings for DARKSEND to come out of BETA before the marketing Blitz begins. This is the only coin that I've held on to for more than a month, all I can do is wait. That 112 BTC buy wall was not for decoration. People with money to pump the coin have taken notice but why pump it when it is not yet ready?
Yeah it's clear that there are some relatively heavy duty investors circling.
Or somebody wants you to think that...
I would usually bet that it's a fake wall to make you buy from the very same person who fakes the buy order but doesn't really plan on buying any more (except some small amounts to make the history charts more appealing and to clear out the small sellers from the table). But in this case, I tend to believe that some people really wish to play in big and speculate on the effect of the DarkSend feature. Or even not just speculate, but they actually plan on using the coins for real word payments (through DarkSend, when anonymity is desirable for them), not just buy at low and sell on high as soon as possible.
DarkSend has the potential to be a valuable thing. So, even if it won't work out as planned, the promise of it can increase the demand. Both fake and real (most coins only scratch the fake part).
But with that in mind, even the DarkSend feature itself could be a tool to make you buy (and will never actually work as planned). You might never know until everything becomes history.
