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

Blockstream Green

What works

A cosigning key behind two-factor authentication, so a thief with your unlocked phone still cannot spend
The cosigner cannot trap your coins: a CheckSequenceVerify timelock hands each deposit back to your key alone after about 360 days
An open source recovery tool exists for the case where the 2FA service is permanently switched off
Runs on iOS, Android (Google Play and F-Droid), Windows, macOS and Linux
Pairs natively with Blockstream Jade, so the keys can live on a device instead of the phone
Open source, no documents required, and it can connect to your own node over Tor

What to watch

New 2FA Protected accounts have not been available since May 2025, which is the feature most people came for
Keeping 2FA protection on older coins means redepositing them before each timelock expires
Not bitcoin only, and Liquid balances depend on the Liquid federation rather than on bitcoin's mining
The cosigning server sees a 2FA wallet's transactions, a privacy cost single signature does not have
Three names in circulation (Blockstream Green, the Blockstream app, Multisig Shield) make guides and support articles hard to line up
