We looked into the option of accepting cryptocurrency as a payment method but came up against too many obstacles. Without being able to prove the provenance of client funds we would be at risk of breaching "proceeds of crime" / anti-money laundering regulations.
And while the value of cryptocurrencies bounces all over the place and makes it impossible to budget, even stablecoins present problems. While they are pegged to something, the question is to what. Those pegged to precious metals such as gold or silver were a no-no, and even those pegged to the dollar present a problem. (As an aside it obviates one of the cited advantages of bitcoin - as a hedge against monetary policy-driven inflation). The question our board came up with was, if the currency is pegged to the dollar, why not just accept dollars? At least with established currencies we can buy currency hedging. With stablecoins, we'd be looking at specialist forex hedging, or messing about with futures. The board looked at the cost-benefit for about five minutes before they threw it out.
