Some coins have risen 50,60,70 % or more.
I believe it has to do with a Peoples Bank of China announcement

Read carefully, looks like the chinese government wants to use a digital currency in a different way
Now is NOT the time to not be on a mainstream exchange.
It gives me curiosity as where most alt coins prices are increasing to the roof, CSC has not increased that much. Its price has been mostly in decline (according to coinmarketcap) I wonder why. And if China releases a digital currency, then it would affect Bitcoin and the rest of the alt coins, as the Chinese play an important role in these markets.
With cryptsy imploding, it wiped out 99% of active buyers and sellers. So we end up with 2 incredibly thin books on alcurex and alterdice. Now the price has declined because buying only happens when new BTC comes in. BTC that was cycling on cryptsy is effectively destroyed. On the sell side, we still have an onslaught of miners generating 28,800 coins per day and they just care about getting BTC, so they instasell.
Unfortunately, I think we will see a lot of volatility for months in all alts due to the cryptsy fallout. It's just not a healthy functioning market right now.
