There is some very popular coin launched 27th of April. It brought innovative PoW+PoS thing, coin's algo is x11. It had record net hash from start, huge volume at bittrex(also, price 2 times hit 4k satoshi) and the 10% daily PoS will start soon. Adding this coin to mintpal is a question of time, I think you will add it sooner or later, but if you do it now - people will bring incredibly high volumes to mintpal to trade this coin, giving you high profits, especially with buy before 10% daily start thing. People need bigger exchange to trade SUM.

155 pages at that young coin thread. Could be new BlackCoin, don't you think?

At the moment, volume has been lowered because of preparations for PoS(everyone have sent SUM to their wallets). All PoW coins were mined within 2 days, instead of 7. Doesn't that remind you of another successfull coin?
