Glassnode’s “alt-season signal” officially turns bullish—our core view is that after BTC has risen, the breadth of the altcoin sector finally catches up.

This is a structural shift from August’s one-way BTC rally to the “full bloom” across the board by the end of September.

① If you previously missed the BTC move, alt season may be a chance to catch up—but the entry point is higher;

② The alpha in alt season isn’t in BTC itself, but in the “sector rotation order”—typically first L2/DeFi, then meme, and then RWA/AI as new narrative themes emerge;

③ The real late-stage alt-season signal is the combination of “BTC’s share falling rapidly + broad-based altcoin rallies,” indicating that capital has already spread into the lowest-liquidity names.

During this phase, the stock-picking logic should shift from fundamentals to on-chain metrics such as “trading volume + number of active/holding addresses.”
