They are honestly all fairly easy to use.
Using wallets doesn't have that high of a learning curve.
You have an address, you have your keys, and you use them to move money around.
For beginners, I guess mostly they want one that has a nice looking interface.
If that is the case, I would recommend Exodus wallet.
It is a desktop wallet that has a really good looking interface and can hold a wide variety of coins.
But, desktop wallets and web based wallets are pretty insecure.
I would just get a hardware wallet like a Ledger or just do paper wallets.
If you don't know what these are or how to do them, there are hundreds of easy, How To guides on the internet.
Just google, "How to make a paper wallet for cyrpto" or something like that.
Well, it's true we can also ask for help on google for this problem, if I suggest the wallet for beginner is myetherwallet, because now myetherwallet can be used as a storage of coin assets, but if you are more
secure you can use an external wallet because this is trusted.
