People will still use passwords like "password123" and "goraiders" which will cause them to lose their money, but instead of worrying about that, let's worry about the most obscure non-risk we can come up with:

- Alien technology in the blockchain?
- 51% hash pool "attacks"
- Quantum cryptography
- Breaking ECSA
- Breaking SHA256


Did I forget any ridiculous non-risks?
 
Sorry, I have to go spend some bitcoin from my web-based single-factor un-backed-up wallet now.
