Tracking in Your Own Language and Currency

You do not spend dollars. You spend rupees, or euros, or naira, or reais, and yet almost every crypto price you will ever see is quoted in dollars, by an app whose default assumption is that this is fine.

It is not fine, and the gap it creates is larger than most holders realise. Your portfolio contains two positions whether you chose them or not: the coins, and the dollar. When you read a gain in your own currency, you are reading both, mixed together, with no label separating them.

Why is everything priced in dollars?

Because that is where the liquidity is. The deepest crypto markets trade against the US dollar or against dollar-pegged stablecoins, and every other quote is derived from those. When an app shows you a Bitcoin price in Turkish lira, it is not reading a lira market of any consequence. It is taking the dollar price and multiplying by a lira exchange rate.

This is why the same coin can look slightly different across apps even before you get to currency: aggregators build their dollar price from different venue sets, and then each applies its own FX source on top. Two conversion layers, two chances to disagree. Why the same coin shows two different prices covers the first layer; the second is usually smaller but not always, particularly for currencies with thin or managed markets.

Local exchanges complicate it further. If you buy on a domestic exchange in your own currency, that venue's price often carries a premium or discount against the global dollar price, driven by capital controls, local demand or the cost of moving money in and out. The tracker shows you a converted global price. Your actual local sale might not land there.

What does the FX layer do to my reported gain?

Consider two holders who bought the same coin on the same day and sold on the same day.

One is in the United States. The coin went from $100 to $120 and their gain is 20%. Straightforward.

The other is in a country whose currency strengthened 10% against the dollar over the same period. The coin still went from $100 to $120, but each of those dollars now converts into 10% less local money. Their gain in the currency they actually spend is roughly 8%, not 20%. Nothing about the asset differed. The unit of measurement moved underneath them.

Run it the other way and the effect reverses. A holder whose currency weakened 15% against the dollar sees a reported gain well above the dollar gain, and may conclude they made a good call about a coin when what actually happened was a bad year for their currency. That is the more dangerous case, because it flatters the decision rather than punishing it.

Anyone holding stablecoins should notice something here. A dollar stablecoin has no crypto volatility and full currency exposure. For a holder outside the dollar zone, "moving to stables to reduce risk" swaps one risk for another rather than removing it.

How should I set my display currency?

Set it to the currency you will eventually spend, and leave it. Tracking your portfolio in your local currency walks through the setting itself.

The reason to leave it alone is discipline. Switching display currency when one of them looks better is a way of choosing your own scoreboard, and a scoreboard you choose after the fact tells you nothing. Pick the honest unit first.

There is a case for occasionally reading the dollar figure alongside it, though, and it is not vanity. The dollar number isolates the asset's performance from the currency's. If your local-currency gain is 30% and your dollar gain is 12%, you now know that most of what you are looking at is FX, and that FX can reverse. Keeping cost basis straight matters here too: record what you actually paid, in the currency you actually paid it in, because that is what your records need to say later. Cost basis vs. market value covers why an incomplete basis produces nonsense profit figures regardless of currency.

For comparing crypto against other things you could have held, the same principle applies to the benchmark. Crypto vs. gold and the S&P 500 is a dollar-denominated comparison by construction, and a reader outside the dollar zone should mentally apply the same FX adjustment to all three lines rather than to the crypto one alone.

What about the app itself being in my language?

The interface is available in 12 languages, which covers reading the app rather than reading the market. Coin names, tickers and news headlines come from their sources and stay as they are, because a translated ticker would be a worse ticker.

That distinction is worth holding onto. Localisation makes the tool usable; it does not make the information local. A news feed drawn from around 68 publishers is still mostly reporting on markets and regulators in a handful of jurisdictions, and if you hold in a country with its own rules about exchanges, capital movement or taxation, no global feed will reliably tell you about them. Crypto research sources covers building a reading habit that includes something closer to home.

Tax is the sharpest version of this. What counts as a disposal, which currency gains are measured in, and whether crypto-to-crypto trades are taxable all vary considerably by jurisdiction, and a tracker's profit figure is a portfolio number rather than a tax number. Tracker vs. tax software draws the line between the two jobs.

The habit worth building is small. Once a quarter, look at your portfolio in both units, your own currency and dollars, and note the difference. Over a year that difference will tell you something useful about how much of your result came from the assets you picked and how much came from where you happen to live.
