The ultimate collectible.

Ballet’s new Bitcoin BLOCK is a bitcoin collectible masterpiece, created by turning Bitcoin “digital gold” into physical form, made of advanced titanium as used by the aerospace industry. It is designed as a physical square block, to represent a real world version of a block in the ever-expanding blockchain. We created the Bitcoin BLOCK specifically for savvy bitcoin investors who want to hold a piece of history in their hands. Over time, as the block rewards continue to go down by half every four years, the value of this product will surely go up, and there will be real prestige in owning a whole Bitcoin block in physical form.

  • Full Bitcoin Block Reward
    Bitcoin BLOCKs contain the entire coinbase reward of a newly-mined block. This includes both the base block reward of 6.25 BTC as well as all transaction fees mined in that block.
  • Virgin Bitcoins
    The bitcoins come straight from our mining pool partner, mined directly from the coinbase transaction in each block, straight to your physical Bitcoin BLOCK, with no intermediate hops. These bitcoins have no prior transaction history, and thus provide the highest level of privacy.
  • Physical Bearer Asset
    Bitcoin BLOCKs are physical bearer assets, with no external dependencies such as passwords or third-party accounts. Whoever has physical possession of the Bitcoin BLOCK controls the funds.
  • Two-Factor Private Keys
    Bitcoin BLOCKs are made using Ballet’s innovative Two-Factor Key Generation (2FKG) process, which utilizes the industry standard BIP38 process to split the private key into two components (the BIP38 passphrase and the encrypted private key). Bitcoin BLOCKs are manufactured in two separate steps in two different locations around the world. This provides what we consider to be the highest level of private key security for the customer.

Ordering Procedure

Important: all Bitcoin BLOCKs are made-to-order, so we will not have any additional inventory for sale later if you do not place your order directly with Ballet now. Before you place your order, please read the following carefully to fully understand the whole ordering process.
Bitcoin BLOCK is a combination of physical product and bitcoin mining service, so that in order to receive the product, the customer would need to pay both the mining service fee and the mining deposit after payment of the product in the order checkout process. This means Ballet will NOT separately sell the unfunded empty Bitcoin BLOCK for USD $99 without the mining service.
On the Ballet official store at order checkout, the customer pays a non-refundable USD $99 for the product cost of the Bitcoin BLOCK. To place an order, the customer must provide the following details:
  • Full name
  • Delivery address (all details, including: street address, apartment unit, postal code, country)
  • Mobile phone number
  • Email address
  • Customer-created 8-digit order PIN code that will be used to authenticate email communications.
  • Bitcoin refund address to receive the excess BTC amount from the mining of the block. Please note that this refund address CANNOT be changed after the order is placed. Please be sure you control this bitcoin address, and make sure it will be valid for use, as the excess deposit refund could take some time to process.
After the order is placed, Ballet will send an email to the customer (from providing two bitcoin deposit addresses: one for the mining service fee (0.6 BTC) and one for the mining deposit for the block reward (7.5 BTC). IMPORTANT: To authenticate this email as legitimately coming from Ballet, we will reference both the order number and the 8-digit order PIN code provided by the customer during the ordering process. For further confirmation, this information will also be sent via SMS to the customer’s mobile phone number.
Once the payment request email is sent to the customer, they are now required within 48 hours to make two separate bitcoin payments to the two bitcoin addresses provided in the email and SMS:
  • 0.6 BTC for the mining service fee.
  • 7.5 BTC as the mining deposit to the mining pool to mine the block reward directly to the physical Bitcoin BLOCK.
Once the bitcoin payments are received, Ballet will ship the unfunded Bitcoin BLOCK to the customer by express courier. The customer will need to confirm delivery of the Bitcoin BLOCK in order to proceed to the next step.
After the customer confirms physical delivery of the Bitcoin BLOCK, the mining pool will mine a new block with a coinbase transaction sending the entire block reward and all transaction fees directly to the Bitcoin address of your Bitcoin BLOCK.
After the Bitcoin BLOCK is funded, the customer will be informed of the block height and exact amount of BTC, which can be verified directly on the Bitcoin BLOCKchain. If the funded amount is less than the 7.5 BTC mining pool deposit, the excess amount will be sent back to the customer’s BTC refund address provided in the initial ordering process. (If in the unlikely scenario that the total mined amount is higher than 7.5 BTC, the customer will have to send in additional BTC to cover for that amount. If this happens, additional instructions will be sent out.)
Once we know the actual block height and the full block reward amount, we will create a custom set of badges (high quality metal letters) to denote the actual block height and block reward amount. We will then send this set of metal badges to the customer to affix onto the Bitcoin BLOCK. Detailed instructions will be included.
In addition, we will also send a product certificate of authenticity to the customer after the block has been mined. You will be notified by email when these items are sent to you. And optionally, the customer can also request a PGP-signed email from Bobby Lee, to show provenance and certify the Bitcoin BLOCK as genuine. Details of the custom Bitcoin BLOCK will be stated clearly in the PGP-signed email.
As the Third Bitcoin Halving already took place on May 11, 2020, we can no longer produce the 12.5+ BTC Bitcoin BLOCK any more. For more details about that product, please click here.

BTCC Mint Legacy

Bobby Lee, founder and CEO of Ballet, was previously the co-founder and CEO of BTCC until its acquisition in early 2018. Mr. Lee was the creator of the BTCC Mint series of physical bitcoin collectibles, which are among the most highly regarded in the industry. From 2016 to 2018, BTCC Mint produced and sold physical bitcoins in a variety of different physical formats, from coins to blocks to poker chips. Altogether, Mr. Lee produced over 22,000 physical bitcoin collectibles at BTCC Mint, containing over 8,700 BTC in total value.
With Mr. Lee as Founder and CEO, Ballet has inherited BTCC Mint’s legacy. With all of the core team members of BTCC Mint on board, Ballet has unique and unparalleled experience and expertise in production of physical bitcoins. We put security and privacy above everything else, and our four-year long track record is evidence of that.
The security of BTCC Mint collectibles has never been compromised. To date, all physical bitcoins created by BTCC Mint either remain intact in the original physical coins, or the bitcoins were transferred safely to other addresses by the owner. No complaints of fraud or security failure have ever been filed or reported. Mr. Lee is proud of this clean track record as Coinmaker of BTCC Mint and will uphold the same high standard at Ballet.
