I think it would depend on the business owners if they are willing to take risks with the volatility of the crypto market. For example, I remember that steam was excepting cryptocurrency as payments for their games and other payable content, and they didn’t like the volatility of crypto and discontinued it, IIRC.

Most of the owners are probably worried about the payment methods and the legal aspect of the crypto currency‘s right now. We’ll see.

If they are scared of the volatility, I think with stable coins, they would be at ease.

P.S. I don't know what ”poss” have to do with crypto
