Bitcoin Core4.7Bitcoin-only

One of the oldest bitcoin wallets still shipping, strong on Android with deep UTXO control, and an iPhone build nobody has verified.

Pros and cons, side by side

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

Mycelium

What works

  • Shipping on Android since July 1, 2013, one of the longest unbroken runs of any mobile bitcoin wallet
  • Real UTXO control on a phone: unspent output visibility, fee bumping, watch-only and single-address savings accounts
  • Passed all seven of WalletScrutiny's wallet tests, including public source code and an unobfuscated binary
  • Hardware wallet support for Trezor, Ledger and KeepKey, plus spending directly from paper wallets
  • Direct APK download, an Obtainium link and a published signing certificate, so Google Play is not the only way in
  • Optional Tor and your own node, with each third-party service able to be turned off on its own

What to watch

  • The iPhone app trails badly: WalletScrutiny lists 3.22.0.2 for Android against 2.10 for iPhone
  • Mycelium's iOS source repository on GitHub is archived, with no commits since June 2024
  • WalletScrutiny says no iOS build has ever been reproduced, so the reproducibility claim covers Android and not iPhone
  • WalletScrutiny discloses that its own authors have contributed to Mycelium, so its verdict is not fully independent
  • No longer bitcoin only: Ethereum and ERC-20 accounts add code a bitcoin-only wallet does not carry
  • Dated interface, and support runs through a single email address with no live channel
