there will nobody can easily predict the market value. therefore, regardless of the truth, some coins even bitcoins are in down price on first half years, and it will be up on the last of the year. it almost happens every year.
Not totally sure that this year is for altcoins because not all the time and situation of market is good. Maybe not now but later sooner it will be. Just wait for the right time, somehow it become a big "BOOM" to each and everyone.
