I wouldn't put it like that. I would actually, instead, take a look at the market caps of both of the currencies that you are comparing. A lot of people who look at bitcoin as an investment also compare it to the Apple stock, which has the highest market cap. However, even though bitcoin is not just an investment but also a currency, I have not seen it compared to numerous fiat currencies because it's just not as versatile as they are right now. Once bitcoin has more support in the markets, then potentially it can be compared to the USD.
