In the fast-paced world of cryptocurrency, opportunities to acquire significant quantities of Bitcoin (BTC) over-the-counter (OTC) are both rare and highly coveted. Institutional buyers, family offices, and ultra-high-net-worth individuals (UHNWIs) now have access to an exclusive BTC OTC offer involving a total of 120,000 BTC—available in tranches—through a trusted private seller. This Big Block deal operates on a direct, peer-to-peer structure and uses a streamlined set of “handshake” procedures, designed for security, transparency, and executional speed. At the heart of this offer lies a compensation model widely known in the industry as “8/5”.

What Does “8/5” Mean?
The term “8/5” refers to the built-in compensation structure for intermediaries and brokers involved in the transaction. It means that a total of 8% of the transaction value is allocated to commissions, with 5% going to the sell-side and 3% to the buy-side. This structure ensures that all parties introducing and facilitating the transaction are fairly rewarded, while also keeping the deal attractive to both buyer and seller.
For example, if a tranche of 25 BTC is sold at market price, 8% of the total deal value is allocated to the intermediary chain—typically split between brokers, introducers, mandates, or anyone legally listed in the SPA (Sales and Purchase Agreement).
This “8/5” structure is common in high-level cryptocurrency transactions and is typically defined upfront before any wallet addresses or tickets are exchanged. It’s a key element in OTC deals, offering transparency and eliminating disputes later in the process.
How the Handshake Procedure Works
The transaction begins with the buyer providing a USDT wallet address. This is not for payment at this stage, but for verification purposes and escrow clarity if needed.
The seller then provides a BTC wallet and a “handshake ticket”, which acts as a cryptographic signature or nonce to confirm the seller’s ownership of wallet and intention to transact.
Once the buyer receives the ticket, they perform the handshake, usually by confirming the wallet via a small test transaction or validation step on-chain.
Following this, both parties enter into an SPA (Sales and Purchase Agreement) or commercial invoice, laying out the tranche details, pricing terms, and procedures for delivery and payment.
The seller then sends 25 BTC to the buyer’s wallet, initiating the first tranche. Upon confirmed receipt of funds on the blockchain, the buyer pays in full, typically in USDT or another agreed stablecoin or fiat equivalent.
This process is then repeated with increasing tranche sizes, ensuring trust is built while gradually scaling up to the full allocation—up to 120,000 BTC in this particular offer. The term “r/e” stands for “repeat and extend,” which refers to the option to repeat the tranche cycle and extend the total transaction size under the same terms.
Final Thoughts
Big Block OTC deals like this one represent a unique window of opportunity for serious buyers looking to gain or transfer substantial BTC holdings without disturbing public exchange liquidity or incurring slippage. The 8/5 structure ensures that deal facilitators are incentivized to operate with integrity and efficiency.
