How so? I've heard the same multiple times for both 2015 and 2016.
Eventually "this year will be the year" will be right... Heh.
Seriously though, why assume that BTC has to see 1000% growth again? It already has a healthy, upward trend. Besides, all altcoins that eventually gain recognition see that same exponential growth at first. Be happy with 100-150 dollars/year price increase.
