The way I see it when looking at
www.coinmarketcap.comRipple is centralized BS, not to be touched
Litecoin is not innovative and has been dieing off for years
Dogecoin is a joke, a good one
Maidsafe might not even work
Paycoin is a scam
Stellar I don't know about
NXT is shady and a bad model
Darkcoin is overly engineered and flawed, SDC has a better method for anonymity
Bitshares solves all the problems critics love to slam on bitcoin, volatility, centralized mining, wallet addresses, etc etc
I can't wait to see what this list looks like by end of 2015 but in my mind Bitshares will remain at top with bitcoin for a very long time.
