Bitcoin Surges to One of Its '10 Best Days' as Sigma Move Hits Record

Bitcoin's recent surge has left investors wondering if it's here to stay. According to Fundstrat's Tom Lee, the week was one of Bitcoin's '10 best days.' This is significant because research shows that these explosive sessions account for nearly all of Bitcoin's long-term gains.

Lee pointed out that investors who stepped aside waiting for a lower risk missed these handfuls of explosive sessions. In fact, Fundstrat's data reveals that the 10 best trading days since 2014 have provided a positive 162% in cumulative returns, while the remaining 365 days averaged negative 14%.

Ethereum (ETH), Solana (SOL), Hyperliquid (HYPE), and Zcash (ZEC) also posted gains alongside Bitcoin. Lee highlighted that Ethereum spot ETFs drew $189.15 million on Thursday, the largest single-day inflow in 10 months, calling it 'a good sign' for ETH.

Wall Street veteran Jody Visser noted that Bitcoin's weekly move hit a +7.12-sigma reading, surpassing previous spikes in 2019 and 2023. A sigma move measures how far a price swing deviates from its recent norm, with anything above 3 considered extremely rare.

Bitfinex analysts suggested that the rally was built to last, citing spot buying and short covering as the main drivers rather than fresh leverage. They warned that investors should 'hold on for dear life' (HODL) given the momentum upwards.
