While there may be an argument to be made as to how Bitcoin is cheaper and equally is convenient, it is doubtful Walmart would accept cryptocurrency payments. Unlike Visa, Bitcoin has little traction, as there is no real reason for consumers to get involved in cryptocurrency. At the same time, if a brand like Walmart were to accept Bitcoin, it could boost the adoption rate of cryptocurrency in the US and Canada.
