Multiple large 10+ btc buy orders being flashed and the sell orders are beginning to thin out.  It might be nothing or some new btc might have arrived to market.  Either way its fun to watch, as I'm not all that interested in selling my CANN.  Every dump on the way up helps increase distribution, of course some people will need to take profits on the way resulting in disbursement of their bulk holdings.  In the long run this is a good thing. IMHO

edit: also looks like someone miight have bots working hard again
