Practical overview

When it fits

Use it when you want a command-line snapshot of configured holdings and market data rather than a graphical portfolio interface.

Who it is for

  • People who want a terminal-based view of cryptocurrency holdings and estimated portfolio value.
  • Users comfortable cloning a JavaScript repository and installing dependencies with npm.

Documented uses

  • Record coin quantities in a local JSON portfolio file.
  • Review portfolio value and each holding’s net worth.
  • Compare allocation percentages in a horizontal bar graph.
  • View coin rank, price, volume, market capitalization and recent percentage changes.
  • Request data in a supported display currency.
Before you choose

Requirements & limits

  • Holdings are configured locally in portfolio.json.
  • Market data is fetched from CoinMarketCap.
  • The README documents USD as the default and currency selection through -c or --currency.
  • The repository identifies its license as MIT.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
