They often do, but I’m expecting a divergence this cycle. The financial industry is setting up to come into bitcoin in a significant way with new ETFs (eg BlackRock) and institutional exchanges (EDX). The alt coins will likely be suppressed from the attack on Coinbase and Binance. So basically bitcoin should outperform.
I went down the ETH rabbit hole for many years until I realized that all roads lead to bitcoin. I focus exclusively on bitcoin now and I just use it as savings. I never trade. Just buy and hold for retirement.
