Gabi,
Thank you for being willing to lead a new comer in the right direction. This is all new to me, looking at the blockchain info service, you can import your private keys there and it will retrieve the keys from the offline wallet and bring them down into the virtual wallet there?
1. Install BTC on your PC, get some BTC into the wallet
2. Generate several paper wallets securely and then send your BTC to those paper wallets
3. Hop on a plane and fly across the world (let's say I head back over to Japan)
4. I land in Narita, clear customs and sit down, pull out my laptop and go to
https://blockchain.info/wallet/5. Use the tool to import each one of my private keys and retrieve the coins from each wallet
6. The wallet in my blockchain info account will now have all of my BTC's originally purchased in Step #1
7. I can now install Bitcoin on that laptop, secure it and transfer my BTC from the blockchain info wallet to that wallet and vice versa, spending it in Tokyo freely
Do I more or less have this right, in how the coins are 'retrieved' from the network once the private key is imported in? If I have this right I think I am officially In Love.
