Just nuke the originals...
No, Mr Bond, I expect you to die.
And this time I won't tell you my plan beforehand just in case you manage to escape.
But seeing as you asked, and I'm a megalomaniac who just can't resist spilling the beans... I'm going to crash the value of Bitcoin by threatening to bring the original Satoshi stash to the market. I'll buy up on the cheap and then announce that I've destroyed the key to the stash, driving the price up again! And there's nothing you can do to stop me!
