Sovereign communities in Europe

The Netherlands' pioneer bitcoin city project, started in 2014, which at its peak signed over 100 Arnhem merchants including a Burger King. Honest status: its payment processor BitKassa shut down under MiCA regulatory pressure, so live merchant acceptance has thinned considerably, though the community, its merchant map, and regular events continue.

Italy's longest-running bitcoin merchant economy, founded in 2015 in Rovereto, Trentino, by Marco Amadori and local entrepreneurs. The area claims the highest density of Lightning-accepting merchants in Italy relative to population, and accepting businesses now hold their bitcoin rather than auto-converting to euros. A quiet, durable example rather than a tourist spectacle.

A network city of coliving neighborhoods founded in 2021, connecting 20-plus independently operated properties across the US, Europe, Latin America, and Asia under shared culture and tooling. It began as a DAO; the broader neighborhood-organizing work has since spun out into the Neighborhood Village Project. Useful infrastructure for nomads, though smaller than its early hype suggested.

The German-speaking world's bitcoin community, grown out of the Einundzwanzig podcast since 2020 into roughly 200 local meetups across Germany, Austria, Switzerland, and neighboring countries. Each meetup is independently organized — no company, no headquarters — coordinated through a shared portal. One of the strongest examples of a meetup network that outgrew its founding media brand.

A nonprofit founded in 2022 to make Madeira a bitcoin island, working with merchants, schools, and the regional government. Over 170 businesses across the island accept bitcoin — about 62 in Funchal — and the group hosts a monthly meetup plus the Bitcoin Atlantis conference. Grassroots and volunteer-driven, though acceptance still leans toward tourist-facing businesses.

A libertarian micronation proclaimed in 2015 on Gornja Siga, a seven-square-kilometer parcel of disputed Danube riverbank between Croatia and Serbia. It issues citizenships, runs blockchain-based governance, and holds gatherings at Ark Village on the Serbian side. Honest status: eleven years in, no UN member state recognizes it and physical settlement remains minimal.

The City of Lugano's joint initiative with Tether, launched March 2022, to make bitcoin and stablecoins part of municipal life. Around 360 to 400 merchants accept BTC, USDT, and the city's LVGA token, taxes can be paid in crypto, and an annual forum draws thousands. Top-down by design — its momentum depends on city hall and Tether's funding.
