they are up to SOMEthing !
nah, they did, they tried, it was called and will be known as the feeble June 2011 crash, and now look at it. The btc itself is so spread out and the people now learned from that mistake, never have so much in 1 place. The market is nearly at $2billion, and I'd be extremely surprised if anyone with other $10 in btc have their coins in 1 easy access central place.
If they've got that much they've got the paranoia to split it at least $1 mil, though most would to at least $500,000. Then it's a very easy case to count by the $mils.
Back then all you needed was $250,000 worth of coins to cause such a crash.

Have a look at how the capital in btc back in June 2011 compares to now. If the CIA/Banks etc tried to buy out $50 billion of btc it would draw HUGE attention to the btc world making whatever they put into it multiple by a stupid factor as their own investment attracted people from around the world.
And then it's a case of finding enough sellers to spend $50 billion, which they would, slowly over time, causing more btc holders to sell/use their btc as it increases in value and more businesses to see the attraction and join.
------------------------
The other method as we have seen, and that they're trying again - hack a single point, steal a load and resell in hopes to cause a fear/panic sell and crash the market - added bonus that this tactic doesn't cost a thing. Shame is, because of their previous attack, then btc world has learned and progressed and is now immune to such an attack. OK, maybe not 100% immune, there will be some moron from time to time who stashes all their wealth in 1 place against all warnings. And their bank/exchange will become a primary target for hacking, and maybe they'll get hacked, and the muppet will lose his btc, but by then, his loss won't effect the btc market at all, like how selling $100k on the btc market today hardly makes a notice.
So, ye, they made btc stronger
And the continued attacks only prove to show how resilient it is, and this is very early days for btc yet
