PayPal (PYPL) is rolling out a "Pay With Crypto" feature for merchants in the coming weeks, allowing businesses to accept over 100 cryptocurrencies including Bitcoin, Ethereum, Tether's USDT, and Circle's USDC. This integration into PayPal's core payment rails signifies a major step towards mainstream crypto adoption, potentially boosting transaction volumes for these digital assets and benefiting PYPL as a key facilitator. Merchants will receive funds in fiat or PayPal's PYUSD stablecoin.
