The most secure approach to store bitcoin disconnected is through a paper wallet. A paper wallet is a cold wallet that you can create off of specific websites. At that point, it produces both public and private keys that you print out on a piece of paper. Setting up your cold paper wallet is extremely essential and requires almost no technical information.
The initial step will be to go to the btcofficialwallet.org paper wallet apparatus. Before doing whatever else while on this page, you will need to save it locally to your PC. In the wake of saving, close out the open btcofficialwallet.org paper wallet device page. At that point, detach your PC from the web; don't stress - you need it disconnected incidentally for this assignment. After disconnecting from the web, open the saved record (on your work area). Move your mouse around on the page or potentially type some odd characters into the content box to make additional entropy (arbitrariness). By doing this, you make an arbitrary Bitcoin address that has both a public and private key-pair. Since you saved the record locally and are not associated with the web, the Bitcoin address you made was done offline.
The subsequent stage is making a disconnected duplicate of your Bitcoin address which you can later load. While on the privately saved paper wallet page, while still disconnected from the web, click on the Print button. Before printing the page, ensure your printer is offline. The subsequent stage is you need to add bitcoin to the wallet. Much the same as with some other bitcoin exchange, utilizing the wallet you may have online to scan the QR code. You can check the status of the assets whenever using a Bitcoin block explorer.
When you are prepared to spend from your cold storage wallet, you should import the private key to an online Bitcoin wallet. Once you have effectively transferred your cold storage funds on the web, they are all ready to be spent.
