If $BTC pumps but most alts are bleeding, you're watching a fake rally.

The index shows price. Breadth shows strength.

When fewer coins advance than decline, only a handful are carrying the weight. The rest? Red.

Math doesn't lie. When breadth diverges, price eventually follows it down.

Retail stares at charts. Pros watch internals.

$BTC up + breadth down = red flag
$BTC up + breadth up = real move

Check the breadth data. What's it telling you right now?
