Yeah it’s sort of time based assuming consistent blocks, but it would still based on confs. If the hash rate doubled then one would only require 30 minutes until the difficulty adjustment kicked in.
The main purpose of my post is that to actually pull off a successful attack you probably need more than an hour, so the numbers are making it look like it’s cheaper than it would be in practice (ignoring other factors other commenters have shared about acquiring ASICS, data centers, and such).
You can’t 51% attack Bitcoin for $611K, but your site says you can. While the site can’t be perfect, it would be helpful to make it more realistic. If a news site picks this up and doesn’t understand the nuances they’ll accidentally spread FUD and mislead a lot of people.
Yes, I’m saying that rather than needing an hour to get 6 blocks if the hash rate doubled, you’d only need 30 mins _until_ the adjustment occurs. Then it would be an hour again.
