You can use it offline also. Basically works as you send a transaction on your offline computer, transfer the data of the transfer on your online computer via usb stick. You don't ever have your wallet online.
Ok so I do not have to be online after plugging in the usb in order to open the wallet and then send coins?
That is giving me a much better feeling, thought I had to be online to send.
Thank you
Although I know it is possible to receive coins while being offline, I thought you had to be online to send coins? Doesn't initiating a transaction require broadcasting it to the network?
I honestly think you're better off with a safety deposit box and some acid free paper. If someone has unfettered access to that room there are far more valuable things than a bitcoin wallet.
Depends if you that the bank staff not to look through your possessions while your gone. While jewellery cannot go missing from a bank safe deposit without some big questions, if some scrupulous staff member copies down your private key/mnemonic they could move the coins without having to steal the actual paper. And with the paper still where it should be you have no way to prove that it was the banks incompetency.
Maliciousness, not incompetency.
