If you zoom out on the bitcoin dominance chart (BTC.D) you'll see the importance of this searing hot white trendline — and the markets are battling once again for direction. There is a possible double top (indicated by the hammers) and price is resting above cloud on the 6 hour chart. A push below the trendline and into the cloud signals a drop in bitcoin dominance. Which means an alt coin rally could be soon.
