In a situation whereby you accept it as a means of payment while selling off your goods, then when you are out of stock, so you decide to restock your shop, so by then price of Bitcoin has dip so much that you can't buy all the goods needed in your shop, due to the fact that your money has depreciate in value because of the dip, what is the way forward in such a situation if your emergency funds can't cover up for the shortage?
I have always not been a fan of accepting Bitcoin as settlement of trade for goods and services but some people like the idea of accepting Bitcoin for settlement which I see as a choice and what you ask really matters. What I know some of the people that accept Bitcoin to for goods and service does is that they accept Bitcoin because they want to accept it and keep, they have extra cash somewhere to restocked their goods and things they sell to customers.
They keep this Bitcoin until another bull market before they sell them off since they would have made alot of return on their investment. Some of them do this things because of love for Bitcoin and not really because of the adoption because it does make sense for a business owner that want to make money everyday and rebuy the items on his shop every day to generate profits for sustenance and take of his bills.
Like you, I don't like the idea of using bitcoin as a means of payment for businesses. As far as I know, not many people like to use bitcoin for payment, most of them just want to keep bitcoin as an investment to earn profit, they are very reluctant to spend their bitcoin. While some people will use a converter and convert bitcoin to fiat immediately after receiving payment, why don't we just use fiat to avoid the hassle?
Also, if they really want to invest in bitcoin, it would be wiser for them to proactively buy bitcoin instead of accepting bitcoin as a means of payment and turning it into an investment. Because in my opinion, if we actively buy bitcoin, we will have the opportunity to buy at a cheaper price.
