Love the idea and I already store all bitcoins as well as alt coins in private wallets. The only time anyone should not protect their crypto assets in a private wallet is if they need to get them to an exchange to conduct business. My suggestion would to store in a Trezor device, Bitshares wallet, and the Exodus wallet.
Thanks for pushing this extremely important topic. I do believe that this is the very reason why many of us got involved with crypto in the first place.
Take out all the thieving middlemen that take a little bite out of OUR pie every time we need to put fiat into use.
