See how your Bitcoin purchases are really doing

Protect Your Coins turns the transaction statement from your Bitcoin exchange into a clear report: how much you invested, how much BTC you hold, your average cost per coin, and whether you are up or down today. It is built for people who buy Bitcoin regularly (dollar-cost averaging) and move it to their own cold wallet.

How it works

  1. Import one or more CSV statements, for example one file per year.
  2. Review the live dashboard: total invested, average cost, break-even price, profit and loss, charts and a year-by-year table.
  3. Export a PDF report, or the cleaned data as CSV or JSON, then erase everything with one click.

Questions and answers

Is my statement uploaded anywhere?

No. The file is read and analyzed by your own browser. It is not sent to this website's server or to any third party, and nothing is saved in cookies or browser storage.

Which statement formats are supported?

CSV exports with a date, a fiat amount and a Bitcoin amount per transaction, such as the transaction history export from Bitcoin Well. Failed orders and reward payouts are recognised and handled separately.

How is profit or loss calculated?

The value of the Bitcoin you hold at the valuation price, minus the money you paid in. The valuation price defaults to the last rate in your statement; you can type a price or fetch the current market price.

What is my break-even price?

Your average cost per Bitcoin: total money invested divided by total BTC bought. Above that price your holdings are in profit, below it they are at a loss.

Does this need access to my wallet or keys?

No. It only reads the purchase statement. Never enter a seed phrase or private key into any website.
