According to Brad Freeman (@StockMarketNerd), Coinbase ($COIN) is introducing a stablecoin checkout and payments product called Coinbase Payments, intensifying competition in the digital payments sector. This move is expected to drive further innovation among established players like PayPal ($PYPL), Shopify ($SHOP), and Apple ($AAPL), as they must evolve to maintain market share. For traders, the launch of Coinbase Payments could increase adoption of stablecoins and influence transaction volumes on the Coinbase platform, potentially impacting $COIN's revenue and the broader crypto payments landscape (Source: @StockMarketNerd on Twitter, June 18, 2025).
