Over the past year, 37% of altcoins in the top 50 have outperformed BTC. Interestingly enough, this isn't nearly as bad as I imagined it to be. But it's also good to be aware that these coins are in the top 50 because they did "relatively" well, and the majors were the better performers overall. The percentage of outperformance would quickly start dropping to <10% as you include the mid, small and micro caps.(Daan Crypto Trades)
