What are the pros and cons of this ? Can this increase sales in the physical store because some would like to spend crypto in bulk which they are getting from some source ?
Using Bitcoin doesn't have a huge impact on sales. Because what they buy using Bitcoin is just equivalent to using fiat money. There is no sales improvement, nor will it encourage people to spend more. What they see is the option of payment, like having a credit card. But despite this situation, at least it shows adaptation. The more stores that open this payment option, the more it encourages crypto users to use their Bitcoin as a form of currency. In fact, that is what we want to see, where it is completely recognized as currency.
