2016 is by no means over yet and it's much too early to draw conclusions. One of the players this statement is true for the most, is Viktor "Isildur1" Blom. After a great year on PokerStars (peaking at +$4.95 million, ending the year at +$3.5 million), Blom had a disastrous start to 2016.
The month of January was relatively quiet for him and the remainder of the year was mostly downhill. Week after week and month after month, PokerNews reported Blom losing hundreds of thousands of dollars. For most of the year, he lead the Top 3 losing players, getting awfully close to a million in the red.
