Correct me if I'm mistaken, but I think you're leaving Bitcoin as a major participant or programmer or coder or services developer. The actual bitcoins in your wallet that belong to you, you should get to keep it.

If you can't trust that you will retain it when you move (because your computer or laptop can get lost or compromised) and you can't afford to have it on paper, then the best way would be to send the bitcoins to the people here.

My suggestion is to consolidate it into one (or a few) private address, print that out, and keep it with your passport. You're not going to lose that. You could also just email it to yourself, encrypted of course.

If you just let it go, then of course, no one else will ever have access to the bitcoins, and it will be eaten up or absorbed by the bitcoin economy.
