Bitcoin (BTC) has added more than 7% in the last 24 hours to about $45,600, the highest level since the start of April 2022. U.S.-traded companies such as crypto exchange Coinbase (COIN), software developer MicroStrategy (MSTR) – which owns a large number of bitcoin – and mining firms Marathon Digital (MARA) and Riot Blockchain (RIOT) rode the bullish momentum to show significant gains in pre-market trading.
