> There are other cryptocurrencies (eg Tether) that follow USD (eg 1 Tether is almost always equal to $1.00 USD), to avoid issues with volatility.
One of us is behind the times on Tether; last I heard they were in pretty significant legal/financial trouble re: money laundering, not actually having most of the backing dollars they claimed to, and possibly market manipulation.
There have been various stories floating about litigation, solvency, and market manipulation in tether. So far, the market [1] remains unconvinced: tether trades pretty close to parity (sometimes even at a premium; liquidity preferences being what they are), and prices between tether-based exchange and USD-based exchanges are also pretty tight. So for the moment accepting payment in tether USD is entirely feasible.
