Thank you so much @stick for doing this. Some answers were incredibly eye-opening.

Another q: Are you worried at all about the fact that the majority of Bitcoin's hashing power has been in Bitmain's hands for years? All machines are naturally connected to the internet, so Bitmain could reach them at any point. Since the hardware is not transparent, we can't assume there are no remote control mechanisms. We can all agree that Bitmain would instantly chop off a branch under them if they ever used anything like this, but this could be exploited by a malicious employee for example.
