Not entirely impractically if you're the US Govt, but very very very expensive  ;D Estimates are around $666m right now, to do a 51% attack [1].

I certainly hope it's US $ and not Zimbabwe $  ;D ;D

Seriously ... It's just too much money for too little gain. Why would any sane person even want to waste that amount of money, to do that.

This is just a non-issue.

Well, some people actually suspect the US govt actually created Bitcoin - https://news.ycombinator.com/item?id=5547423

Probably in the same category of people who believe 9/11 was an inside job though.

Even if you were to successfully launch a 51% attack on the network, the "honest" nodes and miners could simply ignore the blocks that were found by the attacking miners so the 51% attack would ultimately not work.

Also any 51% attack must be sustained over the long term and not just over a few hours or a few days, as the network could simply do a soft fork from when the attack had started if it ends early enough

You could do a 51% attack with a subsidized mining pool and the greedy ass miners.

It would be far cheaper than $666 million :P
