To be frank, i event don't trust bitcoin.org, you know it's not Satoshi who operates it now.
I still recommend Ownbit wallet. (
https://ownbit.io) You can use it as a cold wallet.
such a strange statement about bitcoin.org followed by recommendation of a closed source wallet!
any wallet that has not released their source code, can not be reviewed by anyone, is not reviewed by experts and doesn't have deterministic builds is considered shady and must be avoided. ownbit wallet fails on the first step since it is closed source. and worst of all they have pretty much a useless excuse for being closed source too: "
we are not opening yet for preventing copy & paste from competitors".
Ownbit invented a way to approve it's safety without opening any source code. Below is the steps:
1. Download Ownbit wallet, and then turn off network.
2. Import a mnemonic (You create the mnemonic somewhere else you trust). Then a cold wallet is created.
3. In another mobile (with the network) you create a Watch Wallet. All communications between Watch wallet and Cold wallet are by scanning QR code. And QR code is in plain text and can be viewed and audited.
Your mnemonic is always safe because the cold wallet is always offline.
