Well I think personally I am going to get into as many viable altcoins as possible. Missed the whole crypto-currency train first time round so I am trying to increase my holdings of btc, but also want to get into some altcoins too. I guess with so many out there its hard to know which ones. takes a lot of time to read/research all these coins esp when you have a slave-wage job in the 'real world' lol
It is hard to know if they are viable or not
Most altcoins will fail but I don't fully agree with OP in the sense that I think some altcoins may co-exist with Bitcoins in the future because they will have an active community and a few small different features that suit some people's needs or taste.
