Several high end brands like Christofle Paris and the Bel-Air Fine Art Gallery have already adopted the Aditus crypto payment gateway. It definitely feels like a strategic move in keeping up with the times as they could tap into a new segment of the market (i.e those who hold their wealth in crypto).
On a smaller scale though, would you consider buying something more mundane like a cup of coffee with crypto? Not sure how that would play out with the volatility of the market and other factors.
