My answer is NO, and the dominance chart is the reason why. In a real altseason, Bitcoin dominance falls as money rotates down the risk curve into alts. Right now it's doing the opposite, BTC dominance just broke above 60% for the first time in eight months and is targeting the 66% cycle high. Presently, $BTC moved 1.43% while $ZEC moved 8.54%. Bitcoin's still the one setting the pace, alts are just occasionally outrunning it in short bursts. CoinMarketCap's own Altcoin Season Index backs that up, it's sitting in the high 30s to high 40s, roughly half of the 75 reading that actually defines an altseason. What's really happening is narrower than the topic makes it sound. $ZEC is up around 75% over the past week on its own privacy narrative and ETF filing news, not a market-wide theme. $XRP gained close to 44% over the same stretch on its own catalysts. Meanwhile most other established altcoins posted single-digit weeks and went nowhere. That's a handful of names running hard, not a rotation. There's also a timing problem historically. Altseasons have tended to follow fresh Bitcoin all-time highs, not recoveries from a drawdown, and BTC's still well under its October peak. So this is $ZEC and #XRP having good individual weeks inside a Bitcoin-led market, not the starting gun for altseason. That fires when dominance actually turns down, not when a couple of alts have a strong run while it climbs
