Bitcoin/USD

The overall marketcap for crypto is very low compare to lets say the stock market. The price will continue to fluctuate alot until the real big investors like banks and big institutional investors go in hard. I believe that the marketcap will rice hard sooner or later and thats when the real growth for bitcoin and the other coins will come. The price now is in my opinion low but i would as the other people said invest in eth or even ETN for now since i belive this coins will have a bigger % growth then bitcoin will in 2018. But after all the whole market is just speculation for now, we will just have to wait and see what happens
