The price of bitcoin leapt back above $100,000 to start the first full trading week of the new year.

The flagship cryptocurrency was last higher by about 4% at $102,234, according to Coin Metrics. The broader crypto market, as measured by the CoinDesk 20 index, gained more than 3%. Bitcoin and ether are coming off their best weeks since Dec. 6, while Solana had its best week since Nov. 22.

Crypto stocks Coinbase and MicroStrategy advanced nearly 6% and 5%, respectively. MicroStrategy Monday morning reported it has purchased another 1,070 bitcoins for about $101 million, bringing its total bitcoin holdings to 447,470.

The moves in crypto coincided with a rebound in tech stocks as Nvidia and shares of other chip names jumped. The tech-heavy Nasdaq was last higher by about 1.9%.

Activity is coming back into the crypto market after a post-election rally that was driven by promises of a more supportive regulatory environment. The optimism sent prices rocketing for weeks before cooling at the end of the year. The price of bitcoin is expected to roughly double under the new administration this year, with some price predictions, like Fundstrat’s Tom Lee’s, being as high as $250,000.
