In business if you have bitcoin in such a situation you will get better results if you keep it for long term without taking any risk.
There is still a risk even in the long term. Many just don't realize that we're all taking risk even if we're holding for so long because we've just learned it as our patience taught us to be.
When it comes to payment most people prefer fiat to buy things with cash, but it's entirely up to you. To get something good, people have to work hard. Go ahead with the plan and hold on to the bitcoins instead of selling them.
Just always stock some cash if it's about to support the financing of a business. It's true that most people still prefer to pay things with cash but we're starting to see that the adoption is increasing and therefore, at some point in time, there will be folks that will like to pay in BTC or any preferred crypto to at least support the crypto economy by spending.
