USD withdrawal records: what to keep when a dollar balance leaves in coins

Why do the two units meet at the exit?

Duelbits says all withdrawals are processed in cryptocurrency, whatever the deposit was, and that its units are converted back into the coin you choose. The BitStarz post from March 2020 says the same for a crypto-funded fiat balance: the options are coins, converted in real time. A dollar figure goes in the request, a coin amount comes out.

What are the five records?

The dollar figure on the screen at the moment of the request; the coin and the network chosen; the coin amount that arrived; the transaction hash from the wallet or the explorer; and the date and time. Together they show the rate that was applied, because the coin amount divided into the dollar figure gives it.

Operators change how they review a request, and BitStarz's post mentions a review by support before the money is sent. A record that includes the time of the request lets you tell a review from a delay.

Where to keep them?

Anywhere that is not the operator's site: a note on your phone, a spreadsheet, a folder of screenshots. The operator's history may change its display, and a record kept elsewhere does not.

How do you read the records back?

Divide the coin amount that arrived by the dollar figure you requested. The result is the rate applied, after any fee taken out on the way. Do it for two withdrawals made close together and the two rates should be near each other; if they are not, the gap is a question for support, and you will have the numbers to ask it with.

Keep the same habit for deposits. The pair of records, one going in and one coming out, shows what the cashier did to your money in both directions, which a single balance figure never will.
