Concealcoin is 100% scam.
How does Cryptsy add a coin so quick, when other coins have paid votes plus regular votes and haven't been added on. My guess is that one of their cronies created the coin, with a short PoW to create panic and hype and a rush on the exchanges to trade the coin.
Then Bittrex/Polo hop on the scam train and list this giant turd.
24HR PoW + Whitepaper scam = hype and huge exchange trading volume. Plain and simple.
These exchanges need to be careful. I know Bittrex and Cryptsy are US Based so if they are complicit to this scam then they can be shut down.
People are asking why the dev would scam if they didn't premine. Well, they don't need to premine if the scammer owns an exchange and makes money from the fees.
