ETHEREUM lagging behind BITCOIN in market cycles?

This is nothing but a simplistic illustration of how Ethereum is currently replicating Bitcoin's 2015 RSI price action.

It is obvious how ETH reproduces the RSI trend pattern of BTC often trailing by as much as 4 years! Can this mean that it is lagging behind Bitcoin in market cycles? If yes then this chart is definitely a road map to be looking into for Ethereum traders.
