Which are the best wallets for total newbies? Anyone who will actually need the advice in this post will need something very easy, so I don't want to list something too difficult.
I feel electrum wallet is just fine, it is open-source and easy to use, and newbies can either run it on their mobile device or desktop, they can also either use it as a hot wallet or for cold or offline storage. Mycellium is another good option that can be included.
BlueWallet is also good for iphone users because electrum is unavailable on ios.
Mycelium has been running ads for 1xbit (at least on Android - the iOS version has been running on an outdated codebase for ages) so I do not trust them tho sell out to the next big scammer one bit.
Electrum is fine. So is Electrum for Android & Trezor.
I have never used Bluewallet before, but I hear that people like it, so I would wait for more vouches for them in this thread before redirecting newbies there.
