This chart is destined to go lower. Not only technically, but also from a pure fundamental perspective. There are simply too many $Alts in the market, and while $BTC will always be the Granddaddy, 11,000+ crypto's mathematically have diluted and skewed this metric. I still chart dominance as an indicator for at least having some idea of when $BTC will "run" and other $Alts might pause. For now, the spotlight is on $BTC (as it should be). $BTC's success will allow other quality coins to also flourish during the final phase of this Bull market.
