Please don't forget it took BitCoin 5 years to get to where it is today, this coin has only just begun and there are 4 very talented developers working on this coin.
sorry but in reality you cannot compare bitcoin with other coins. bitcoin was the first and the only one cryptocurrency on the market. there are milions invested in bitcoin, it does not need to do anything to be popular and useful. and generally it can replace all other coins.
no one coin has so much time, but it need the real special feature which will do the coin to outstanding one.
I think just for Talkoin the BITMASSAGE could be one of this features, please explain what difference is between talkcoin and skype or qq,.. now?
