Buy Claude Pro with Bitcoin

Which BTC network to use

Network choice decides most of what you pay in fees, and getting it wrong is the one mistake that loses funds outright. Match the network shown on the invoice exactly.

The case for paying with BTC

• The most widely held crypto asset — many buyers have BTC and nothing else.
• Easiest to acquire through non-exchange channels: ATMs, OTC desks and person-to-person trades exist for BTC where they do not for stablecoins.
• Fully decentralised issuance, with no issuer capable of freezing an address.
• Lightning, where available, is as cheap and fast as anything else on this site.

The case against

• Highest fee of any option at subscription size, and the fee is unpredictable because it depends on mempool congestion.
• Ten to sixty minutes of confirmation time, during which the BTC price can move enough to underpay the invoice.
• Underpayment because of price movement is a real failure mode and requires manual reconciliation.
• Spending appreciating BTC on a $20 subscription is a poor trade for most holders — this is the classic pizza problem.

Where to get BTC

• Any exchange, ATM or P2P desk — BTC has the broadest acquisition surface of any crypto.
• If you already hold BTC on an exchange, consider swapping to USDT-TRC20 first; the swap plus a $1 TRON fee is usually cheaper than a congested BTC transfer.

When Bitcoin is genuinely the right choice

If BTC is what you hold and converting it would mean onboarding to an exchange that will not accept you, then the fee is simply the cost of access and it is worth paying. That is a common situation for buyers in sanctioned or heavily-restricted jurisdictions, where BTC is acquired peer-to-peer and stablecoin rails are harder to reach.

It is also the right choice if your processor and wallet both support Lightning, which removes essentially all of the objections above. Check the invoice — if a Lightning option is offered, take it.

Outside those cases, converting to USDT or USDC before paying will usually save you more than the swap costs.

Why the Bitcoin fee you are quoted is a guess

Bitcoin fees are not set by the network — they are a bid. You are competing with everyone else broadcasting a transaction at that moment for space in the next block, and when the mempool is busy the price of confirming quickly rises sharply. This is why fee estimates on a subscription-sized payment can swing from under a dollar to well over ten within a day.

Your wallet estimates a fee that should confirm within a target number of blocks. Setting it too low does not fail the transaction; it leaves it sitting unconfirmed, sometimes for hours, which on a time-limited invoice is its own problem.

• Check a mempool fee estimator before sending rather than accepting the wallet default blindly.
• For an invoice with a rate-lock window, pay for a faster confirmation. Saving two dollars on the fee and missing the window costs more.
• Quiet periods are genuinely cheaper. This is not superstition — demand for block space really is lower.

If your transaction is stuck unconfirmed

An underpaid-fee transaction sits in the mempool rather than failing. It has not been lost and it has not been spent; it is simply not attractive enough to include yet. There are two ways out, and which you have depends on how the transaction was constructed.

• Replace-by-fee (RBF): if the transaction was flagged replaceable, your wallet can rebroadcast it with a higher fee. Most modern wallets enable this by default.
• Child-pays-for-parent (CPFP): spending the unconfirmed output with a high-fee transaction gives miners an incentive to confirm both. More involved, and not offered by every wallet.
• Waiting: fees fall, and a stuck transaction usually confirms eventually. Unhelpful when an invoice window is expiring.
• A transaction that never confirms is eventually dropped from the mempool and the funds become spendable again. They are not gone.

The price-movement risk that stablecoins do not have

This is the strongest practical argument against Bitcoin for this specific purchase. Ten to sixty minutes of confirmation time is ten to sixty minutes during which the BTC price can move, and the invoice is denominated in dollars. A payment that was exact when you sent it can arrive underpaid because the market moved against you while it confirmed.

Payment processors handle this with a rate-lock window and a tolerance band, but the tolerance is finite. On a volatile day an underpayment is a realistic outcome, and it converts an automatic order into a manual one. A dollar-pegged stablecoin removes this failure mode completely, which is why we recommend one to anyone who has the choice.

Paying with BTC, step by step

1. Choose your plan and term on the checkout page — the price is itemised so you can see the gift cost, our markup and the processor fee separately.
2. Enter the email address where you want the redemption code sent. It does not have to match your Claude account.
3. Select BTC as your payment coin. The invoice shows the exact amount and the address.
4. Withdraw from your wallet or exchange on the network the invoice specifies. Send a small test first if the amount is large.
5. Watch the status page — it polls every few seconds and updates as the payment confirms.
6. An operator buys the official gift subscription by hand and emails you the code, within ${site.slaHours} hours and usually much sooner.
7. Redeem the code at claude.ai/gift/redeem on the account you want upgraded.
