I wouldn't say it was an enormous mountain of precaution for me to store my btc in my own wallet. It's kind of the point
I expect to lose more from btc's value crashing than some elite conspiracy of hackers having sabotaged my hardware & somehow working out my private key which isn't stored in plaintext
If I was holding a really great worth of btc, going the full mile of cold storage would make sense. At that point you're invested, quit kidding around
Semi-related, it’s wild to me that the best practice for a digital currency is the functional equivalent of keeping your money in your mattress.
