Yes. Bitcoin isn’t the same as traditional money, its value can fluctuate significantly in a short period. For example, during 2021 one Bitcoin started at $60,000, dropped to $30,000, climbed back to $58,000 and then dropped back to $20,000.  In short, if you accept Bitcoin and then use it straight away there is very little risk. However, if you hold onto it, the value of your Bitcoin may rise or fall. That could mean you have sold your products for less than they are actually worth.
