This year is hard to rise as fast as last year, and there are too many bubbles in the market, and if some of the ICO random access to the market does not disappear, it's hard to have new investors willing to enter the market.
Actually no one is certain if the market this year would be good. It is hard for some but there are still willing to enter the market as months cam might go up its value. There are still a possibilities price of bitcoin can increase but were not certain if same as last year.
