Tuesdays Have Been Bitcoin's Most Volatile Day in 2025
Market participants anticipate heightened activity, influenced by global economic trends.

What to know:
- Bitcoin has experienced its highest realized volatility on Tuesdays throughout 2025.
- March has also been the most volatile month since the start of 2024.
In case you haven't looked, it's Tuesday. For bitcoin traders, that could mean some big price swings.
According to Amberdata, Tuesdays have been the most volatile day of the week thus far in 2025, particularly over the past month, where realized volatility has averaged 82.
Realized volatility measures the standard deviation of returns from the market’s mean return, reflecting past price fluctuations. In contrast, implied volatility represents the market’s expectations of future price swings.
Amberdata also looked at monthly volatility and since the start of 2024, March has had the highest at 67.
Amid bitcoin’s recent 30% drawdown from its all-time high, its one-month annualized daily realized volatility nearly hit 70 versus an average of about 50. The only two other instances of similar volatility spikes occurred in March 2024, following another run to a record high (then $73,000), and in August 2024, during the yen carry trade unwind, according to Glassnode data.

Small investors are buying bitcoin. For a rally to succeed, the whales need to join in.

Small wallets have increased their BTC holdings by 2.5% since October's all-time high while large holders trimmed 0.8%, Santiment data shows.
What to know:
- Bitcoin wallets holding less than 0.1 BTC have increased their share of supply to the highest since mid-2024 even as the price holds around the mid-$60,000s.
- Larger holders with 10 to 10,000 bitcoins — the whales and sharks that typically drive major moves — have reduced their positions since the October peak.
- The divergence supports choppy, fragile price action because retail demand alone cannot sustain rallies when big wallets are distributing into every recovery.
