It's called variance. It will either go up or down. However, the general trend of Bitcoin is upwards so it's easier to argue that it's more likely to go up in value. So accepting Bitcoin as payment is +EV in my opinion.

However, some businesses currently could suffer if they accepted Bitcoin due to it's volatily. If you're selling SAAS your cost is tiny so accepting a more +EV payment currency is probably beneficial.

However if you're selling physical widgets on very slim margins and don't have anything in place to reduce your exposure via quick selling of Bitcoin, and cashflow is/could be an issue it's probably not suitable.
