BankingBitcoinbank21 Set

Released once. To one buyer.

§ 01 — Reading the name

Bitcoin and bank describe the service; 21 refers to the fixed limit of 21 million bitcoin, a number holders recognise instantly. Together they read as a bank built around a hard supply cap. The .app ending is a generic ending intended for applications and served over HTTPS only, so the address itself tells users to expect software on their phone or in the browser, protected by encrypted connections by default.

The address belongs to the bitcoinbank21 series within the Bitcoinbank21 set; the same name is also held on further endings, including .com, and the series can be acquired together. A buyer with a main brand on another ending can use the .app address for the product itself: a mobile banking app, a web wallet or a customer portal.

§ 02 — Who it is for

Three projects this name fits.

Mobile Bitcoin banking app

The download and landing page for a phone-based Bitcoin account with savings, payments and card features, reached through one address that names the product directly.

Browser-based wallet

A web application where customers manage bitcoin balances, send payments and review statements, served under an ending that requires encrypted connections.

Product page of a group

A Bitcoin bank whose company site sits on another ending can reserve this address for its app, keeping corporate and product communication cleanly separated.

§ 03 — The same name, other endings

bitcoinbank21 — held on 7 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 choose a .app address for a Bitcoin banking product?

The ending sets an expectation: users see .app and assume software they can open, install or log into. Because the ending is HTTPS-only, encrypted connections are built into every page, which suits a financial product. A team can run the app here and corporate information on another ending.

How does buying bitcoinbank21.app 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 bitcoinbank21.app be acquired together with other names?

Yes. bitcoinbank21.app is part of the Bitcoinbank21 Set bundle and the same name is held on further endings. You can make an offer for the single domain, for the same-name set or for the whole bundle.

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.
