Execute the Bitcoin purchase

Every step until now has been planning. This is the step where the company actually deploys capital. Because the trade involves wiring real money, receiving a volatile asset, and moving it into custody, the risks are highest here — slippage on the trade, operational errors during transfer, or compliance gaps in the paper trail.

Buying Bitcoin at treasury scale is not the same as buying it on a consumer app. Think of it like closing on a commercial real estate deal versus buying groceries. You don't just show up with a card. There's a process — escrow, inspections, wire transfers, signatures. The same is true here.

Step 1 — Pick an execution partner

For any meaningful institutional purchase, the company works with either an over-the-counter (OTC) desk or a regulated exchange. Both have their place.

• OTC desks — best for large block trades. The desk negotiates a price with you directly, off the public order book, so the market doesn't move against you. This is how most $10M+ purchases happen.
• Regulated exchanges — Coinbase Prime, Gemini, and similar. Good for smaller transactions or companies that want to work directly on an order book. Reputable exchanges offer institutional pricing and infrastructure.

Whichever partner you choose, look for transparent pricing — usually a VWAP (Volume-Weighted Average Price) or TWAP (Time-Weighted Average Price) execution — so you get a fair, market-informed price rather than a single-point snapshot. Discuss all fees and spreads upfront. Surprise costs are one of the most common ways companies overpay.

Step 2 — Fund and test the settlement

Before the full purchase, run the plumbing once with a small amount. Wire a modest sum to the execution partner, execute a small trade, and confirm everything settles — the wire clears, the Bitcoin lands, custody receives it, and the paperwork matches.

It's a bit like pressure-testing a pipeline before opening the main valve. Small test flows reveal broken joints. The last place you want to discover a routing error is on a nine-figure transaction.

Step 3 — Move Bitcoin to custody immediately

Once the trade settles, the Bitcoin must move — quickly — into the custody model you set up in Lesson 5. That means either:

• Self-custody — transfer to your company's cold-storage wallet (hardware wallet, multisig setup).
• Third-party custody — transfer directly to the custodian's cold-storage address (Fidelity Digital Assets, BitGo, Coinbase Custody, etc.).

Step 4 — Governance and approvals

Every transaction — buy, sell, transfer — needs an approval chain. This is not optional. The core controls:

• Multi-signature approvals — for example, a wallet configured so any transfer requires two of three signatures from the CFO, Treasurer, and Head of IT Security.
• Access control lists — who can even initiate a transaction, who can approve it, who can execute it. These three should not be the same person.
• Real-time monitoring — most custodians offer built-in tools that alert administrators whenever Bitcoin moves. Turn these on.

Step 5 — Record everything

Every transaction becomes an entry in a permanent log. Auditors will ask. Regulators will ask. A future you will ask. What to record:

• Trade logs — execution price, quantity, timestamp, trading partner, fees.
• Custody logs — wallet addresses, custody agreements, key-management changes over time.
• Compliance documentation — tax records, SEC-relevant disclosures, regulatory filings.

The Bitcoin Transaction Logbook — physical or digital — should be treated with the same seriousness as any financial ledger. Every entry timestamped, every backup verified, every signature captured.
