Of course having access to the private key, need to be the most basic way to access funds. It's the only thing that's guaranteed to be uncensorable, while minimizing the requirement of trust. It is a big responsibility though, and should not be taken lightly. The crypto-currency community is partly at fault here, for blaring memes like "If you don't control your private keys, it's not your Bitcoin", without any regard for whether or not people are ready for that responsibility.

That being said, there are number of ways you can store your crypto-currency, with varying degrees of trust-minimization:

- Use a multi-signature smart contract wallet, where a master key has power to move the money. If the master key is lost, the money can be moved by X out of Y keys signing off on the transaction. You can then distribute the Y keys to your trusted associates, preferably without telling them who the other key-holders are.

- Use a dead-hand smart contract wallet, where the money can be retrieved by a trusted associate, if the dead-hand switch hasn't been activated within Z amount of time. Can be combined with the above, in case further trust minimization is needed.

- Store your crypto-currency at a FDIC exchange. Pretty much the same model as the banking world. This really should be the go to way for the average Joe, as it mirrors what you currently can expect from online-banking.
