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

Phoenix

What works

  • A real self-custodial Lightning node on the phone, not an account on somebody's server
  • Fees published as a table on ACINQ's own site: 0.4% plus 4 sat to send, free to receive when you have liquidity
  • Standard BIP39 seed on a BIP84 path, recoverable in Electrum if ACINQ ever disappeared
  • Built by ACINQ, which develops the Eclair implementation and runs a large routing node
  • Rotating taproot receive addresses, with swaps that look like ordinary transactions on chain

What to watch

  • ACINQ's own FAQ says Phoenix offers no privacy advantage over a custodial wallet and that ACINQ knows the destination and amount of payments
  • Receiving without enough inbound liquidity costs 1% plus mining fees, and a new channel costs 1,000 sat
  • No on-chain balance, which makes it a spending wallet rather than somewhere to park savings
  • Recovering from a force close takes roughly 720 blocks, about five days
  • Wake-up notifications rely on Google services, so GrapheneOS users need the sandboxed Play Services app
  • Was off US app stores from May 3, 2024 until some point in 2025, which is why some reviews still call it unavailable there
