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 ?
If you are operating a shop where you accept bitcoin or any other crypto, there is a high tendency that you will attract a lot of youth to your shop since most of them are into crypto, but there won't be much difference if you are not adding anything up to spice up your service, as your competitors can also be doing the same thing. The disadvantage is if you are not using a payment processor and your shop is so small, you might run into losses sometimes if the price of bitcoin drops down below the price your customer paid with.
