I think it is a pain in the arse for businesses due to the high volatility. It makes reporting of revenue a bit of a moving target.
However, there are companies like Crypto.com that are trying to build a link to existing payment services, but it would mean that you received fiat whilst the customer pays in crypto.
I would be using this as a way to build up crypto as a hedge against what I feel is impending massive inflation that must come from all of the stimulus money that has been pumped into the world economies. Inflation is the only way the governments of the world can possibly repay all these debts.
