Shares tied to the cryptocurrency sector experienced a widespread rally on Monday.

Circle Internet Corp (CRCL) surged more than 11%, leading the gains.

Other notable advancers included Bitmine Immersion Technologies (BMNR), up over 8%, and Coinbase Global, Inc. (COIN), Robinhood (HOOD), and Strategy (MSTR), each climbing more than 7%.

CleanSpark, Inc. (CLSK) and MARA Holdings (MARA) also posted solid gains, rising over 5%.

The positive momentum followed a significant uptick in the prices of major cryptocurrencies.

Bitcoin jumped more than 4% to surpass the $66,000 level, while Ethereum soared nearly 10% to break above $1,800.

In corporate news, Michael Saylor, the founder of Strategy, announced via social media that the company had recently purchased 1,587 bitcoins for approximately $100 million.

This acquisition brings Strategy's total bitcoin holdings to 846,842, solidifying its position as one of the world's largest publicly traded holders of the cryptocurrency.

Furthermore, according to a recent chairman's letter from Bitmine, the company added 76,881 Ethereum (ETH) to its holdings over the past week, continuing a pattern of frequent accumulation.

The company stated that the recent price correction in ETH does not reflect underlying improvements in the Ethereum network's fundamentals and expressed a view that the crypto market is in the early stages of a bull cycle.
