The address

The public address on the front works as the identification number of your wallet. Anyone, including yourself, must use it to send bitcoins to your wallet.

You can also use it to check your funds or transaction history. The public address on the front of the wallet can be shared and seen by anyone. The reason why is because it doesn’t give access to your funds but allows people to deposit funds in your wallet.

Where exactly are your bitcoins?

Your cold wallet doesn’t have electric components or any internet connection, so your bitcoins can’t be physically on your wallet; however, every single bitcoin that belongs to your wallet’s address is registered in thousands of computers. This process is how the bitcoin blockchain works.

Your bitcoins are absolutely yours. They are much more yours than the money you may have in the bank (which, like bitcoin, is not really in the bank, as it is just a simple note on the bank’s computer). And there is no better way for them to belong to you.

You can be confident that your bitcoins are safe because, through thousands of computers synchronized with each other, it shows to anyone who checks that your bitcoins are on your plate.

My private key has rust. Is my wallet in good condition?

Rust is a residue of laser marking; your plate is fine. When we mark your cold wallet, the laser generates waste by striking the steel with a highly focused and precise energy beam. That’s why the plate doesn’t look so good in that particular part.

We immediately cover the private key with a metal sticker so that it is not visible to anyone, not even our technicians. 

The rest of the wallet has no residue because we clean it before sending it.

You can also clean it with soap and water or, even better, with an alcohol swab to clean the part where the private key is engraved.

What is the difference between my   MATERIAL BITCOIN‘s private key and address?

The address is public data. You can give it to anyone without fear.

You can check the movements and balance of all bitcoin addresses worldwide, including the address of your Material Bitcoin plate, on the Bitcoin blockchain, which is public. Numerous websites allow you to do this effortlessly.

On the contrary, as its name suggests, the private key is private in nature. The private key to your bitcoin allows you to transfer money to another bitcoin address. For this reason, it is crucial that only you know the private key. Keep it hidden and protected.

Never show your private key to anyone. Never allow anyone to take a picture of it, leave it unattended, or write it down on a web page.

What is the anonymity to buy and hold bitcoin with MATERIAL BITCOIN?

The wallet is sent empty (without bitcoin inside) for security.

Material Bitcoin has not any obligation to report to any organization about the persons who purchase wallets or about how many bitcoins are inside the wallets.
