Requirements & limits

Coinpare is distributed as a Ruby gem. Its installation instructions require Ruby greater than 2.0.0. The public repository identifies the project as AGPL-3.0 licensed.

  • Coin figures default to USD conversion and the CCCAGG exchange; both can be changed with command options.
  • Market comparisons default to the top 10 exchanges for BTC/USD by total volume across all markets in the last 24 hours.
  • Coin and market views support automatic refresh; the documented default interval for coin refresh is five seconds.
  • Portfolio holdings are persisted in coinpare.toml in the user’s home directory.

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