the dollar is stable because it's worth a little less ever month. to say that bitcoin is unsuitable as money because it also goes up sometimes seems to miss the point. but if you onramp and offramp at the time of transfer, then you both have the stability you so desire, and you didn't pay 2%+ on top for the privilege of doing so

Not about if is worth a little less or more, it's about extreme volatility to settle in the future.

i agree if your partner accept it and hold btc on its balances, there is no problem with it. It doesnt make it money too,but a useful secondary moe.
