$ETH /$BTC is starting to look a lot like the setup we saw in 2025.

If this pattern plays out again, ETH could start gaining strength against BTC, and that could be a very good signal for altcoins.

The interesting part is not just ETH. It’s what usually happens when capital starts rotating away from Bitcoin and into higher-beta assets.

One chart can change the whole market mood.

I’m watching $ETH /BTC closely here. If the rotation confirms, altseason could get very interesting.
