NZ$ gets you 0.00069201 BTC at Stacked Bitcoin, after fees.
That’s 69,201 sats. Most converters use a worldwide “spot” price nobody in New Zealand can buy at; this one uses the live buy price and fee at each NZ exchange, so the number you see is the number that lands in your wallet.
The last column is what the gap is worth in dollars, so you can decide whether it’s worth opening another account.
Spot is a worldwide average from big trading venues. A New Zealand exchange has to buy those coins, bring them here and cover its costs, so its price sits a little above spot. That gap plus the fee is what our converter accounts for.
One Bitcoin costs more than a car, so most people buy a fraction, and Bitcoin is counted to eight decimal places. 0.00053108 BTC is the same thing as 53,108 sats: there are 100,000,000 sats in a Bitcoin, the same way there are 100 cents in a dollar.
We re-read every exchange’s public price every 60 seconds. Bitcoin moves around, so the figure you see here and the figure at checkout can differ by a few sats, the last decimal places. The ranking rarely changes within a minute.
