Ethereum will do good for one more market cycle then the decline starts... I don't have anything against Ethereum personally and think Vitalik is an incredibly smart dude, but these 2nd and 3rd generation blockchains going live on main net are bringing a lot of speed with their networks and Ethereum as it stands cannot scale to keep up..I have faith in Vitalik to find ways to make his product atleast prop its price up for a bit longer, but I just don't see Ethereum at #2 market cap 3 years from now.
