Travel names the setting and pass suggests access: a boarding pass, a city pass, a membership card shown at the door. With Bitcoin in front, the name implies that the holder can pay, book or receive benefits with Bitcoin wherever they go. Each word is common English and recognised by travellers worldwide. The .com ending gives the name an international commercial address, which suits a product that crosses borders by definition.
In the travel category the name supports several business models. A card or wallet product for spending abroad, a network of hotels, restaurants and tour operators that accept Bitcoin, or a subscription that bundles discounts for members could all use it. It also suits an agency that organises trips to Bitcoin conferences and to places where local circular economies have formed around Bitcoin.
