Ravencoin will surely surpass lots of coins in the future. Being asic proof algo. Another thing, I heard that devs of ravencoin came from the btc development. That is why it easily came to listed to bittrex. Connection has a lot to do with being listed  on great exchanges. I'm still mining ravencoin even though right now it is on a loosing side. I'm just accumulating as lots of coins as I can.
