Crypto 101: never let anyone have your private key. No-one who religiously followed that rule has ever had their crypto stolen.

Coins go missing from exchanges, which break the basic private key rule. People use exchanges for convenience because as clever as cryptocurrency is, it has no answer to the exchange problem.

Bullshit. No "religious" following of rules can protect you against a zero day exploit somewhere in your system.

I didn't say it always will, just that it has so far.

Actually, there are smart contracts which act as exchanges. Not for all currency pairs yet, but it's on the way.

Crypto 102: regular people will never use cryptocurrencies if they have to guard their private keys without a fallback in place.
