You tube is where I started and multisig is where I am at present.

I am pretty curious and naturally wanted to try multiple cold and hot wallets.

I am keeping it rather simple these days and feel quite secure with multi sig that Casa or Unchained provides.

Here is some solid advice in this article

Casa wallet is pretty good for beginners, you can even upgrade to their multisig solution in the future once you are comfortable with self custody
