It seems to me that entrepreneurs will not yet widely use cryptocurrency in their business. In addition to the slow legalization of cryptocurrency by states and the lack of adequate infrastructure for using it as a means of payment, a high level of price volatility of cryptocurrency, which cannot be reduced, is of great importance. Business loves stability, especially in money. With cryptocurrency such stability is impossible.
Also lots of businesses got burned in Dec 2017, and the ones who withdrew payment by bitcoin, like Steam, are yet to return. I think a lot of them have decided that bitcoin is an asset or commodity rather than a currency. If businesses do adopt crypto, they might choose an alt instead, if they can find an alt that is stable and not volatile (which might be impossible!)
