...the greater percentage of the total BTC supply someone can steal using
any exploit:
- The more BTC's market value will crash, meaning the attack's purpose changes from profit to an arson-like motive
- The more likely that a majority of previous holders reject BTC in favor of a resistant new coin, even if a fix for the exploit is discovered
Fair point. If one had access to this technology, the rational approach would be to slowly siphon off bitcoins in a way that would be extremely difficult to detect, maintaining the market value.
I'm mainly thinking about the arson scenario. If adversaries were able to destroy faith in Bitcoin this way, I'm not sure how much confidence would be left in
any cryptocurrencies.
