Quite a bit of buying and selling on c-cex over the last week or two. Volume seems to be building nicely. Lots of miners selling (because that's what miners like to do so they get paid) but lots of traders buying too. The patterns are certainly interesting to watch. Seems to be 1 or 2 times a day when the price jumps 50-100% or more just because someone comes in and buys up a big amount at once.
