Bitcoin slipped below $42,000 on Friday, stalling below its yearly high.

Shares of U.S.-listed cryptocurrency-related companies sold off heavily on Friday morning as investors took profit on the last trading day of the year after an explosive rally in 2023.

Crypto exchange Coinbase (COIN) declined 8% during the early hours of Friday, while the shares of relentless bitcoin hoarder MicroStrategy, with nearly $6 billion in BTC in its treasury, dropped nearly 7%.

Nasdaq-listed bitcoin miners Marathon Digital Holdings (MARA) and Riot Platforms (RIOT) suffered even steeper losses ranging over 10%. Smaller public miners CleanSpark (CLSK) and Hut 8 (HUT) also fell nearly 20%.

The sell-off was perhaps buoyed by investors locking in profits for 2023, capping an explosive year for the beaten-down asset class as bitcoin's price rally stuck below its yearly highs ahead of an expected spot-based ETF approval in the U.S.

BTC was changing hands slightly below $42,000, lower than its near-$45,000 local top recorded in early December but up 155% this year.
