21bitcoin.exchange

21 + bitcoin + .exchange — the supply cap, the asset, the activity

Trading

Released once. To one buyer.

21bitcoin.exchange pairs the number 21, a reference to the 21-million supply cap, with Bitcoin, and places both on the .exchange ending. The ending completes the sentence: this is a place to exchange. It suits a bitcoin-only trading venue, a brokerage app or an OTC service that wants its purpose written into the address.

§ 01 — Reading the name

Twenty-one is shorthand among holders for the fixed supply of 21 million coins, and putting it first gives the name a quiet signal of conviction. Bitcoin follows plainly. The .exchange ending turns the address into a description of function, read naturally as the 21bitcoin exchange. Because the ending carries the meaning, the name stays short and leaves the part before the dot free for branding. It is an international ending and is not tied to one country.

The domain sits in the trading category. The same name is also held on .group and .shop, and the three can be acquired together, giving one brand an exchange, a corporate holding address and a retail shop. Typical projects: a bitcoin-only exchange or broker, a savings-plan app that buys bitcoin regularly, an OTC desk for larger orders, or a peer-to-peer trading service.

§ 02 — Who it is for

Three projects this name fits.

Bitcoin-only brokerage

A brokerage app offering only bitcoin, with recurring purchases, withdrawals to self-custody and clear fee information, under an address that states its function in the ending.

OTC desk for larger orders

An over-the-counter service handling larger purchases and sales for companies and wealthy clients, with personal contact and settlement into the client's own wallet.

Peer-to-peer trading

A platform where users trade bitcoin directly with each other, with protected trades, reputation profiles for counterparties and a range of local payment methods.

§ 03 — The same name, other endings

21bitcoin — held on 3 endings.

The endings can be acquired together, so one brand covers its markets from the start. Each has its own page.

§ 04 — Questions

Before you make an offer.

Why does the number 21 carry meaning for bitcoin buyers?

The protocol limits total supply to 21 million coins, and holders often use 21 as a shorthand for that scarcity. A trading venue named after the number signals that it is built around bitcoin specifically, which matters to clients who want a bitcoin-only service.

How does buying 21bitcoin.exchange work?

Send an offer with the form on this page or by email. If both sides agree, the purchase is settled through Escrow.com: the buyer pays into escrow, the domain is transferred, and the funds are released after the transfer is confirmed.

Can 21bitcoin.exchange be acquired together with other names?

Yes. The same name is held on further endings, listed on this page. You can make an offer for the single domain or for the whole set.

Is there a list price?

No. Every domain in the portfolio is sold on a Make-Offer basis; the price is agreed per inquiry.

Can I pay in Bitcoin?

Payment in Bitcoin is possible by arrangement, outside Escrow.com — mention it in your inquiry and we will agree on the route together.
