ETH’s 24-hour high-low range is still wider than BTC’s, but the “who’s wider” comparison from this morning is no longer enough.
At 22:40:02 Beijing time on October 3, 2026, using the same USDT quotation and recalculating over a rolling 24 hours with (high−low) ÷ low: ETH is still wider than BTC by 0.42 percentage points. The gap recorded this morning was 0.80 percentage points. The conditions haven’t failed, yet the gap has narrowed—this suggests that “ETH is wider” still holds, but the advantage isn’t as obvious as it was this morning. Here we’re comparing the span between the highs and lows within the window, not the returns between two sampling points; the start and end of the two rolling windows are also different.
For the next self-check, just record two things: whose range is wider, and whether the gap has widened again. If BTC takes the lead again, or if the gap is close to indistinguishable, then this judgment should be rewritten tonight.
