Major retail breakthrough: the nation's largest supermarket chain has begun rolling out cryptocurrency payment support to customers. This move potentially puts digital assets in front of around 150 million shoppers, marking a significant step toward mainstream payment adoption. The integration allows customers to complete transactions using crypto directly at checkout, reducing friction between crypto holders and everyday commerce. This kind of institutional adoption from blue-chip retailers typically signals growing confidence in digital currencies as viable payment methods and could accelerate similar initiatives across other major retail networks.
