The first part, bitcon, is a shortened form of bitcoin that drops one letter and gives the name a distinct, brandable shape. Wallet names the product category directly, the word every holder uses for the software or device that keeps keys. Hub adds the idea of a centre where several things meet: wallets, guides, support and accessories in one place. The .com ending gives the name a neutral international base for an English-language service.
The domain sits in the storage category and belongs to the Wallet & Storage set in this portfolio, a group of names built on wallet, lock, safe and guard vocabulary. It fits companies whose business is helping people hold keys well: a multi-wallet management app, a reseller of signing devices with setup support, a custody help desk or a review and comparison site focused on self-custody tools.
