This news is not as bad as known advantages which can be exploited in PoW for several years now, namely selfish mining, which only benefits the largest or most coordinated miners. This attack is open for all, which effectively cancels out the advantage it offers (assuming everyone does it); the externalization is consistent, minor inaccuracies of time stamps on blocks.
Cryptocurrency never seems to track against real world events. Kinda makes you wonder how much of its volume is legit.
Ah but it does get impacted by things like interest rates and tech stocks.
Very true. And arguably government stimulus checks too.
But bad news? Your crypto coin has a documented flaw that allows it to be manipulated? Good news for your coin!
weird time to make this argument in the wake of the latest cryptocurrency downturn which tracked almost lockstep with the stock market.
As Eth is moving to PoS soon, I'd expect it have to affect Bitcoin's price more.
This does not work on bitcoin. Bitcoin’s difficulty targeting algorithm only retargets every 2016 blocks. This attack is only possible for diff target algos that retarget within a single block slot.
