Pros and cons, side by side

Atomic Wallet

What works

  • Keys are held on your device, so a working install still lets you move your own coins out
  • Desktop builds are published for Windows, macOS, Ubuntu, Debian and Fedora, with a hashsum check for the download
  • One app covers bitcoin and more than a thousand other assets, which is why so many people kept so much in it

What to watch

  • More than 5,500 wallets were drained on June 2 and 3, 2023, for over $100 million by Elliptic's count
  • Atomic has never published a confirmed technical cause, offering four possibilities and picking none
  • No compensation has been paid to the people who lost money
  • Its first public statements put the damage at under 0.1% and then under 1% of users, which the on-chain evidence contradicted
  • The first class action was thrown out in 2024 on jurisdiction rather than on the facts, and a second is now pending in California
  • The homepage says nothing about the incident and still runs testimonials from a man who died in 2021

Bitcoin Core

What works

  • Validates every rule for itself, so your balance does not depend on someone else's server being honest
  • Bitcoin only, with the keys in a wallet file on your own machine and no account anywhere
  • Every vulnerability the project has fixed is published, dated and classified on its own advisory page
  • Free and open source, maintained by a large contributor base rather than by a company
  • Doubles as the private backend for friendlier wallets such as Sparrow
  • Pruned mode still validates every block while keeping a far smaller amount of data on disk

What to watch

  • The first sync downloads and verifies the whole chain, which costs hours and a lot of disk space
  • Desktop or server only: there is no phone app
  • A plain wallet interface with no fiat on-ramp, no price display and no hand holding
  • Running an old version leaves you exposed to bugs the advisory page has already described
