Jack Dorsey-led payments technology firm Block could become a formidable player in the crypto mining industry, but Wall Street will need details on profit margins to gauge the earnings tailwind from this business, analysts said. Block inked its first large-scale crypto mining hardware pact on Wednesday, agreeing to supply its chips to bitcoin miner Core Scientific, but no financial details were disclosed. J.P. Morgan estimates the deal could fetch $225 million to $300 million for Block, but said it will need more information to evaluate the hardware business's long-term earnings potential.
