Its illegal and I suggest you don't do it. Maybe post the key to this fine forum and see if anyone minds helping you move the coins. What a thread lol
Hahaha.

Nice one. <thumbs up>
Thanks for the laugh leepfrog.

Now, what's even funnier is seeing all the pretentious folks out here.
As for the 'scenario', consider for a moment, you find the private key for a wallet containing 40+
BTC, what to do?
1.Take it, move the funds where you have sole control of key, then do whatever. It's yours.
2. Take it, move the funds where you have sole control of key, donate some, and the rest is yours.
3. Take it, move the funds where you have sole control of key, try to find owner, return if sufficient proof is given otherwise donate all.
4. Don't take it, and let the others claim the
BTC and do what they will.
Most would do Number 1, Some would take Number 2, While those rare ones would do Number 3.
As for 4? Those are for the stupid ones, doesn't want to get involved, or truly doesn't care.
