The biggest crypto by market cap rallied 10% in every week, outperforming the broad-market CoinDesk20 Index’s (CD20) 8% advance, extending its relentless rise from $38,500 in late January. The surge was coupled with accelerating inflows into U.S. spot bitcoin exchange-traded funds (ETF), with BlackRock’s IBIT raking in over 28,000 bitcoin this week.
