I have a strong filing that Bitcoin has its limits and sooner or later will be changed with something more advanced. So to benefit from this process I'm going to build a portfolio of 5-10 promising altcoins to hold it with a horizon of 2-3 years.
From the first look, I'd choose something like: Emercoin, Monero, Waves.
Any suggestions which altcoin platform has a real value big enough to support a growth at this timescale?
