Needless to say, my offline Armory newly installed on a laptop is empty now and contains no money in it, but in the online Armory installed on my desktop (working together with the bitcoin-qt) there's some money because I've just sent them into it from my another bitcoin wallet.
Now I want to transfer the money in the online Armory to the offline laptop, (may need a USB flash stick again?) but the problem is that I don't know how to do it. (May be I'm a damned fool!)
Anybody can render me help? I need actual steps need to be done one by one.
The first person having given useful tips here shall get 0.5 BTC as reward, but not until I can solve the problem of course - no cure, no pay.
No kidding.
This has been answered in the Chinese forum: you don't need to "transfer" your bitcoin to a particular computer because your bitcoin is a record in the blockchain, not in your computer. This is a common misconception of newbies.
Blockchain is a database of all bitcoin transactions in the history. Every computer running a full node (e.g. bitcoind, bitcoin-qt) has a copy of blockchain.
If you want to check the account balance of your offline acounts, just go to blockchain.info or blockexplorer.com. Or you can use a watch-only wallet on an online computer.
I don't know if this counts a "solution" because the question itself is faulty. Anyway, you may send some tips to 1CiZPrEJdN4FJcqdLdgVLzT8tgCXxT5ion if you find my answer useful
