Archon Ledger

Introducing Archon Ledger!
This is a simple, open source software for tracking the value of your crypto portfolio.
It only uses the internet to check prices, and does not reveal your addresses.

The software is effectively a specialised spreadshet.
It is incredibly useful for diversified investors because it tells you exactly how much to buy or sell of each asset to rebalance your portfolio.
