So far this has been the case. When bitcoin dominance goes above 70% at the beginning of the bear market and doesn't go below 35% during the hype of the bull, it's hard to imagine another protocol (not to mention a project) influencing as much the market, for the time being.
We do have the bitcoin and alt seasons (general rule: bitcoin first, alts after). There are alts that may influence the price in the market for some time based on what happens in their ecosystem, but nothing like bitcoin so far.
