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 ?
Fiat is still highly regarded and using Fiat right now as a means of payment is still effective and people have no complains doing so as their sales has still been ok.
Although I will say if you run a physical store and still operate online and you have customers with from different countries then the use of Crypto-currency can increase your sales as transaction made with crypto are more easier, faster and considerably cheaper.
