Hi Product Hunt — I'm Volodymyr, and I build Perly. Perly App is a portfolio ledger for people who hold bitcoin for the long run. It never asks for exchange API keys or a seed phrase: you enter your fills yourself, or import a CSV from Binance, Coinbase, Kraken, CoinGecko or CoinMarketCap. From those fills it works out: - average cost, realized and unrealized profit and loss, and ROI - a yearly report with average cost, FIFO or LIFO - charts drawn from your own history: the stacking chart, a calendar of your buys, and a PnL calendar Amounts, prices and notes are encrypted in your browser before they are stored. It also sends bitcoin price and market alerts by browser push or Telegram, can watch a wallet by its public address or xpub, and installs on your phone as a web app. 18 languages. It's built for bitcoin and tracks nearly two hundred other coins too. It's free for 14 days from sign-up.
