- What is crypto correlation?
- Correlation measures how closely two coins' daily moves line up, from −1 (one rises exactly when the other falls) through 0 (no link) to +1 (they rise and fall together). We calculate it from each coin's daily percentage returns over the days both have a close.
- Which crypto is least correlated with Bitcoin?
- Over the last 90 days it is HBAR at 0.38; over all our data see the table above (select the Bitcoin heading to rank every coin against it). Rankings move from quarter to quarter, so check the window you care about.
- Does holding several coins diversify risk?
- Less than it looks. The average pair of the largest coins has a correlation of 0.54 across all our data and 0.54 over the last 90 days, so most coins tend to fall on the days Bitcoin falls. Correlations also tend to rise in sharp sell-offs, which is when diversification is wanted most.
- What counts as a high correlation?
- Roughly: above 0.8 is very strong, 0.6 to 0.8 strong, 0.4 to 0.6 moderate, 0.2 to 0.4 weak, and under 0.2 close to none. These are rules of thumb; the number only describes the period measured.
- Why correlate returns and not prices?
- Two prices that both trend upward over years look correlated even if their day-to-day moves are unrelated. Using daily returns removes the trend and asks the real question: when one coin has a good or bad day, does the other?
