U.S. crypto-related stocks looked set to start the week on a positive note after bitcoin {{BTC}} climbed through $72,000 for the first time since mid-March as its reward halving draws closer.

Coinbase (COIN), the only U.S. traded crypto exchange, added 4.9% in pre-market trading, MicroStrategy ( MSTR ) , the largest corporate holder of bitcoin, rose 10% and BlackRock’s bitcoin exchange-traded fund (IBIT), added around 6.5%.

The CoinDesk 20 Index, a measure of the broader crypto market, rose 3.1% over 24 hours.

Among miners, Marathon Digital ( MARA ) added 5.2% and Hut 8 ( HUT ) , which merged with USBTC at the end of last year, gained 5.6%. Argo Blockchain ( ARBK ) , trading on the London Stock Exchange ( LDNXF ), rose 5%.
