'''Denarium physical bitcoins''', also called '''Denarium bitcoin coins''', are physical bitcoin coin wallets created by a Finnish Bitcoin company [[User: Prasos|Prasos]] (Prasos Ltd, Jyväskylä, Finland) that contain an embedded piece of paper with digital Bitcoin value, covered by a tamper-resistant hologram. They can be purchased at Denarium's website, https://www.denarium.com (multiple payment methods accepted: Coinpayments, Visa, Mastercard, IBAN/SEPA bank transfer).

Denarium bitcoin wallets are collectible luxury items, suitable as gifts and used for bitcoin investment. They are a helpful tool to save bitcoin, by making multiple transactions to the wallets. The hologram on the physical bitcoin also provides an option to buy bitcoins loaded on the coins or gold bar. When you buy bitcoin with your order they will be automatically loaded unto your physical bitcoin for you.

The piece of durable paper inside each coin and gold bar has a private key which forms the backing for the Bitcoin value represented by the coin. The private key is in 30-character mini private key format. Redeeming the private key back into digital Bitcoins is currently available with a patched reference client as well as with many alternative clients such as Mycelium.

Whenever you redeem the [[private key]] you receive the bitcoin value contained in the wallet, and afterward, the physical bitcoin no longer has any Bitcoin value. It is difficult or impossible to read the private key on the coin without damaging or destroying the hologram, which exposes a honeycomb-like tamper-evidence pattern when peeled.

Denarium physical bitcoins are similar to any form of cold bitcoin storage and are similar to [[Bitbills]] and [[Casascius_physical_bitcoins|Casascius physical bitcoins]] in that they are an object that contains a redemption code that serves as a bearer item for digital bitcoins. They are unique bitcoin wallets, made of different materials and are the first to provide a multisig option for physical bitcoins.

'''Denarium physical bitcoins''', also called '''Denarium bitcoin coins''', are physical bitcoin coin wallets created by a Finnish Bitcoin company [[User: Prasos|Prasos]] (Prasos Ltd, Jyväskylä, Finland) that contain an embedded piece of paper with digital Bitcoin value, covered by a tamper-resistant hologram. They can be purchased at Denarium's website, https://www.denarium.com (multiple payment methods accepted: Coinpayments, Visa, Mastercard, IBAN/SEPA bank transfer).

Denarium bitcoin wallets are collectible luxury items, suitable as gifts and used for bitcoin investment. They are a helpful tool to save bitcoin, by making multiple transactions to the wallets. The hologram on the physical bitcoin also provides an option to buy bitcoins loaded on the coins or gold bar. When you buy bitcoin with your order they will be automatically loaded unto your physical bitcoin for you.

The piece of durable paper inside each coin and gold bar has a private key which forms the backing for the Bitcoin value represented by the coin. The private key is in 30-character mini private key format. Redeeming the private key back into digital Bitcoins is currently available with a patched reference client as well as with many alternative clients such as Mycelium.

Whenever you redeem the [[private key]] you receive the bitcoin value contained in the wallet, and afterward, the physical bitcoin no longer has any Bitcoin value. It is difficult or impossible to read the private key on the coin without damaging or destroying the hologram, which exposes a honeycomb-like tamper-evidence pattern when peeled.

Denarium physical bitcoins are similar to any form of cold bitcoin storage and are similar to [[Bitbills]] and [[Casascius_physical_bitcoins|Casascius physical bitcoins]] in that they are an object that contains a redemption code that serves as a bearer item for digital bitcoins. They are unique bitcoin wallets, made of different materials and are the first to provide a multisig option for physical bitcoins.

The hologram is a high-quality custom-made security seal which is produced in Canada in a specialized high-security facility. It functions as an added layer of security for the protection of the private key. The hologram significantly increases anti-fraud security making it extremely difficult to counterfeit without leaving any visible marks.

The holograms are labeled individually in distinct series, the E-series and the L-series. The E-series are sold as empty, meaning they are not loaded with bitcoins, and the customer can autonomously load a desired amount of bitcoins to the coin. The L-series are sold as loaded meaning they contain a set amount of bitcoins, but the customer can still autonomously load more bitcoins to the coin. The hologram has a “window” where a portion of the public Bitcoin address of the coin can be read for checking balance and loading bitcoins to the coin.

'''Private key'''

All of our coins have a Bitcoin private key inside the coin. We use a 30-character mini private key format. Each private key is printed only once and for security reasons each phase of product assembly that involves the handling of private keys is directly supervised either by Henry Brade (CEO) or Viljami Räisä (CPO), or both.

To make redeeming the bitcoins inside easier, we print the key not only as plain text but also as a QR code. Modern smartphones are capable of scanning the QR code inside and importing the key directly to a Bitcoin wallet such as Mycelium.

'''Activation'''
[[File:Activation.png|300px|thumb|right|Denarium Activation]]

To prioritize security Denarium has built an [https://status.denarium.com/ activation system] with which you can manually verify a coin for bitcoin use. Customers receive a shipment code and email code. Combined they give access to the activation system. Activation It is an extra check done by the customer to verify that the coin is in good condition before loading the coins with bitcoin. It is important that the hologram has not been tampered with during shipping and worthwhile to make an extra check to verify that. Coins that are bought loaded from Denarium will only be loaded after activation. Empty coins can always be loaded with bitcoin, activation for empty coins merely functions as an extra check.
