Major retail milestone just hit the market. Walmart, serving roughly 1 billion monthly customers globally, is now accepting Bitcoin and Ethereum payments directly at physical store locations. This isn't some experimental pilot—it's live across the retail giant's network.

Why this matters? When a company operating at this scale opens the door to crypto payments, it signals genuine infrastructure maturity in the space. We're moving past the 'will crypto ever be useful for commerce' phase into 'how fast can adoption scale.' Bitcoin and Ethereum transition from pure digital assets to actual payment rails for everyday transactions.

The retail sector acceptance typically cascades. One major player normalizes it, others follow within months.
