Bitcoin as the first cryptocurrency was not just created for investment purpose, it was actually created as a means of payment and to be honest, the adoption process isn't as fast as expected, but one thing that am very curious about and I have been thinking on how to go about it as a business man while accepting it as a means of payment is it volatility, though it might be advantageous for holders, but am not that certain for a business men.
In a situation whereby you accept it as a means of payment while sell 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?
Yeah, it was created as a means of payment, but due to its scarcity and how it is mined, people found it much more suitable using it as a store of value than using it as a regular currency. Bitcoin is also accepted in most places where cryptos are accepted but there are other coins that are much better when it comes to making payments due to fees and confirmation time. To answer your question, yes bitcoin is volatile and it is not a good idea for merchants to hold bitcoins. That is why most payment gateways that processes bitcoin transaction allows the merchants to instantly covert bitcoin to other fiat currency or at least to a stable coin. The merchants also has a choice to keep a % of the money received in bitcoin. A smart merchant would keep most of their 'profits' in bitcoin in order to maximize their profits in the long run.
