I'd throw in "Quantum computers" into the discussion but considering that commercial versions are 20+ years away from reality, it's more likely that people will be alerted by some Google Project Zero researcher who finds and discloses a flaw in ECDSA, than by any brute forcing a bunch of crackers are doing

However, we'd make a good benchmark on how practical the exploits are for random people to pull off.

Yes, I was thinking about QCs as well. In fact, it is quite likely that some undisclosed powerful machine managed to find the #120 after searching for smaller ranges on the blockchain. Quite possibly without being aware of this forum.

I would say that a science lab team would not actually send the BTC - they normally follow good ethical standards.
