Keep your bitcoins offline. You know, cold storage, paper wallet, whatever. When you're in London, you can sell it there to someone. By that time, you'd double or triple what it was worth.
Or send it to everyone who posted here, divided as you see fit. I'm a nobody, but if you're leaving bitcoin, help a newbie out? (This is how I got twinked in an online game a long time ago, someone was leaving, and I was the lucky Level 1 character in the same area that inherited Level 50 equipment.)

Thanks.
P.S. I can sign a contract that says "Don't touch my bitcoins until 10 years from now, but we'll split it then when I get back."
Then I will destroy every computer that has the private key after printing it on paper, engrave it on stone or something, then hiding it in a hole. I live in Asia, in a third world country, with a battalion of armed guards/soldiers. I have a wife and a kid, so I'm not going anywhere. Your bitcoins are safe with me.
I am going to distribute all of my bitcoin assets to people I feel helped me get to the position I am at.
Was an announcement necessary? lol
Yes, it was. I owe it to the parties involved in the deals I have partaken in and to the shareholders of the GLBSE asset which I co-operate with Smickles. I can't just get up and leave without letting people know what's happening, why it is, and how I plan to deal with it.
