Call it strange coincidence, but when BTC was down from the all time highs last year, there was no Game of Thrones season, that would have probably broken the pattern. So looking at this trend, we can hope that we see a fairly market during this Season of Game of Thrones as well. Even though this analysis may seem strange, but its nevertheless an interesting correlation. Valar Dohaeris!
