Altcoins Near Key Support, Possible -20% Drop before reversal ?

Sharing my analysis on the altcoin market cap (excluding BTC, ETH, and stablecoins) compared to BTC over the past 10 years

I have marked important zones (yellow circles) where altcoins have historically bounced after strong corrections.

Current Outlook:
- I expect a possible -20% more downside, bringing it near 0.22, which aligns with a key historical support zone.
- This level has acted as a strong base multiple times, in 2018, 2020 and 2021

What I’m Watching:
- If price reaches that zone and holds, it could signal the start of the next altseason.
- Past patterns show similar moves before big reversals.
- However confirmation through volume and market sentiment is important before making any move

Final Note:
Not financial advice, just sharing what I see on the chart. If the ratio hits 0.22 and shows strength, it could be a key level to watch. Thanks
