Re: How to end Bitcoin with as little as 15% of hashpower efficiently
the more interesting (and hypothetical) part is: what happens after the difficult adjustment, after all the hashpower comes back at a very low difficult
what happens after they come back at low diff should be the next 2016 blocks will be mined very fast. So 2 weeks of mining in maybe a day or two (depending on how big the difference). So actually everyone would mine like mad in case the attack doesn't kill it, right?
This is certainly more interesting now.
