Is Bitcoin your unit of account?

Maybe one day, for me it isn't. It's still too volatile (and that's a good thing for our bags, but a bad thing for a UoA).

Do you look at fiat values when you do Bitcoin operations? I do, everyone does, you probably do too.

So the BTC/XMR chart is less interesting, as the value of either side of the pair is not reliable enough to think about.

So I look at the USD charts, which makes a lot of sense, since that is how I gauge the cost of things in real life. And most likely, it is the same for you.
