How it works

Reading the board

The top of the page has the two numbers most people came for: the cheapest place to buy USDT right now, and the place paying the most to sell it. Underneath, every exchange is listed with its own top offers so you can see how far apart they are.

The spread

The spread is the difference between the best buy price and the best sell price. If you bought and sold straight back, that gap is what the trip would have cost you. A narrow spread means a busy market. A wide one usually means either a quiet hour or a market that has just moved sharply.

The official gap

The official rate is what the currency feeds publish. The street rate is what people are really paying. The percentage between them is the number that tells you the most about the day, and it is shown on the front page rather than buried.

How fresh the numbers are

Rates are refreshed roughly every minute and a half, and the age of what you are looking at is printed next to it. If every source is unreachable at once, the last good board is shown with its age rather than an empty page, because a number from four minutes ago is worth more than nothing when you are standing in front of somebody.

Limits and minimums

Peer to peer offers carry a minimum and a maximum, and both are shown where the exchange publishes them. A brilliant rate with a minimum far above what you are changing is not a brilliant rate for you.
