Coin move calculator: what the same coins are worth on two dates
The coins did not change. The daily close did. Pick the amount, the market, and the dates. The closes load when you ask.
How it works: the page asks Coinbase for the daily candle on the USD market. It values the same coins at the first close it gets back and at the last close. The day is UTC, not your local midnight. This is one exchange's close, not your fill, and not a worldwide official price. A registered account does not freeze the price. The three markets are the ones this page can look up.
A price can fall while you still hold the coins
The worked story, with made-up prices, is on same coins changed value. This box uses the live daily close instead. A tenth of a coin at $100,000, then $80,000, is the shape of a loss. Your dates will not match those two prices. How to read a brokerage statement shows a fund or a cash line. It does not show coins that sit on an exchange.
