What coins or tokens are likely to outperform Bitcoin in the short, or medium term? It may have escaped attention that many alternatives doing well against $ are decreasing their value against BTC. Many examples of coins that have seen very large increased this year, if you had stayed in BTC you'd have done better. So what coins will perform better to make diversifying out of Bitcoin worthwhile?
Outperforming as in: Marketcap, Price, Volume, etc?
Personally I think it would be wise to have Ethers for the long term, since it's still at its baby steps and heavily being developed.
