What are the strongest altcoins showing correlation with Bitcoin's price movements?

Over roughly the last 6 months, the **most BTC‑correlated major altcoins** (by daily returns) have been **Ethereum, XRP, Solana, Chainlink, Stellar, and Cardano**, all with correlations ≈ **0.83–0.90** vs Bitcoin. --- ## 1. Top BTC‑correlated altcoins (recent 6 months) Using daily % returns from **2025‑09‑05 to 2026‑03‑03**, for large/liquid USD pairs, these are the **top 10** by Pearson correlation vs **BTCUSD**: | Rank | Symbol | Coin | Corr vs BTC | Overlap days | |------|--------|-------------|-------------|--------------| | 1 | ETHUSD | Ethereum | **0.90** | 179 | | 2 | XRPUSD | XRP | **0.88** | 179 | | 3 | SOLUSD | Solana | **0.87** | 179 | | 4 | LINKUSD| Chainlink | **0.85** | 179 | | 5 | XLMUSD | Stellar | **0.84** | 179 | | 6 | ADAUSD | Cardano | **0.83** | 179 | | 7 | DOGEUSD| Dogecoin | 0.78 | 179 | | 8 | BNBUSD | BNB | 0.77 | 179 | | 9 | AVAXUSD| Avalanche | 0.76 | 179 | | 10 | ARBUSD | Arbitrum | 0.75 | 179 | **How to read this:** - A correlation near **1.0** means the altcoin’s *daily returns* move very similarly to BTC. - **0.75–0.90** is *very high* for markets this volatile — these coins are effectively **leveraged beta plays on Bitcoin**, not diversification. --- ## 2. Example: BTC vs ETH in practice Here’s how **BTC and ETH** prices (indexed to 100 at the start) have moved over the same period — they track each other very closely. ```reference [{"id":1,"type":"plotly-json"}] ``` Key takeaways from the chart and numbers: - Both **trend in the same direction** and turn at roughly the same times. - ETH typically shows **slightly larger swings** (higher beta) around BTC’s moves. - For short‑term trading, BTC moves often **lead or coincide** with similar‑direction moves in these top-correlated alts. --- ## 3. What this means for you Given your focus on **short‑term price drivers and trading**, a few practical implications: - **Not diversification:** Holding BTC plus highly correlated majors (ETH, SOL, XRP, etc.) usually **doesn’t reduce risk**; you’re mostly stacking BTC‑like exposure. - **High‑beta plays:** If you’re trying to **amplify BTC moves**, these high‑correlation alts (especially SOL, AVAX, DOGE) can offer **bigger percentage swings** on the same macro move. - **Event trading:** When you expect a BTC move (macro news, ETF flows, halving narrative), this group is where you typically see **fast spillover** and copycat moves. --- ## 4. If you want to go deeper If you’d like, I can: - Re‑run this correlation over a **different window** (e.g., 30/90 days) to see how stable these relationships are, or - Screen for **lower‑correlation** alts if your goal is diversification rather than BTC beta. 🤔 **Are you mainly looking to find high‑beta “BTC followers” to trade short term, or are you trying to locate altcoins that *don’t* just move with Bitcoin?**
