I thought your point was it was never happening? I provided examples where it did happen in the past and where its happening now. Volatility of the price vs USD is not the biggest issue if the payment processor gives the vendor USD back after the transaction. If the vendor believes in crypto, they can decide to keep it as well. Had Valve chosen to hold their crypto earnings in 2016 for a few years, they’d have seen even larger profits. But thats beside the point. I personally believe they canned it more because of transaction fees. At the time, bitcoin network was oversaturated due to an explosion of popularity which reduced it to unusable levels for everyday transactions.

You should be focusing on why other vendors are still supporting crypto and asking yourself why.
