> a bitcoin wallet encrypted with a good password, it's very easy to make impossible

There's the problem with adoption. "SFYL you should have been smarter" means there will always be a % of the population who should never use it.

Nothing is impossible in the digital realm. And the bad guys are ALWAYS better than the good guys.

Surely, but that requires more knowledge and care than securing cash.

Producing a long random string to use as a password? Not particularly.

Most people have no idea what a long random string would even look like.

I think you're seriously underestimating most people. "Long random string [of letters and numbers]" is rather self-explanatory.

Dealing with nondevelopers, never say "string". Did that once and the person on the other end of the phone was obviously confused. After 2 seconds, realized how bizarre it sounded.

I think you're seriously overestimating most people's ability to think when presented with anything remotely computerish.
