TBH I don't pay much attention to that. I just see that it's around 60% at the moment so when I saw USD at around the same measurement I made a quick assumption. 

I generally think that BTC.D is BS because most of these sh$tcoins are worthless. Sometimes it draws my attention when sh$tcoins are "out performing" Bitcoin.

> Dollar dominance is similar to bitcoins dominance

These terms require more clarification.

Presumably by "dollar dominance" you meant the USD's share among state-issued fiat currencies, and by "bitcoins dominance" you meant BTC.D? (which includes non-state issued fiat currencies, a.k.a. altcoins, including stablecoins)

Dollar dominance is similar to bitcoins dominance (if you believe in that metric).

Is USD the Bitcoin of fiat?
