Who cares about this forum? Only alternates people have heard of, in the real world which matters, is Litecoin and Doge. I'm thinking people would sooner go over to Litecoin than to a coin with a mascot of a big fat yellow dog..
Nobody has heard of Ripple. Ripple tried to do "deals" with many banks and companies, like Wells Fargo and Western Union, and yet it felled through each time. Ripple has been doing these pump and dump announcements for years. Ripple being located in the US means it'll probably get the eGold treatment. Ripple already had a huge fine from FinCen.
Nobody has heard of Ethereum. The Ethereum media machine is already slowing down (ran out of money) and only thing they ever really did was publish articles on cryptonews sites read by dozens and hundreds. When the initial launch hype wears off, Ethereum will be joining Bitshares, NXT and the other 2.0s in capitalization & volume.
Monero? Shut the f*ck up!
Clearly the Bitcoin killer will not come from Bitcointalk and won't be listed on any cryptocurrency exchanges. It will simply bypass this subculture.
