It will only increase sales if there are so many Bitcoin users in the neighborhood or area that the physical stores are operating from. The only way to find out is to make it known to customers that you now accept Bitcoin, you can put a signage in your store because that would be necessary to inform every customer and even passersby that the store is accepting payments in Bitcoin and other cryptocurrency. When that is done, you can then start to keep track of the sales you make via Bitcoin payments and the traditional payment and like I said, you will have more sales in crypot if only there are many crypto users in the area. For the pros and cons, crypto is a volatile digital money and the physical store owners needs to know how they would manage the situation.

I was wondering, if I purchase a gallon of olive oil from a physical store and the oil sold for $50 and I paid the money In Bitcoin equivalent, after leaving the store, the price of Bitcoin plunges badly, would the store owner not be in lose? That's the situation am referring to, such situation should be something that the store owner should know how to manage.
