The community helps people find others and resources about Bitcoin. It is not a single commercial service: a link to a group, partner offer or fundraiser does not by itself establish results or the reliability of every participant.
Jednadvacet describes gatherings over beer, family picnics and lectures. It also links to Twentyone World, which emphasizes lasting open communities in local languages and explicitly distinguishes itself from a meetup calendar. Connected directories do not constitute central management of local groups or authority to change Bitcoin rules. [Jednadvacet — local community directory] [Twentyone World — community network scope]
At review time the homepage lists 46 cities and provides local contacts. Cities are not a count of active members, event attendees or merchants accepting bitcoin. Individual experiences published there are personal testimony, not an independent impact study or a guarantee that trading with a member is safe. [Jednadvacet — local community directory]
The calendar page embeds a Google calendar and offers subscription through a calendar application. Adding an event requires an email request; automatic publication is not promised. Check the date, venue and conditions with the organizer before travelling. This review checked the directory page, not every event within the embedded calendar.

The Studuj Bitcoin article dated 12.1.2026 by Apin organizes links to converters, charts, statistics and network exploration tools. The author intends to select free resources without registration while acknowledging services closing and domains changing. This is neither a permanent guarantee of external website terms nor an audit of every tool. [Jednadvacet — Studuj Bitcoin (12 January 2026)]
The finance page offers support applications for Bitcoin activities and donations through on-chain payments or Lightning Network. It also describes donating part of one's mining power through Braiins Pool with daily payouts to the community wallet. An application does not automatically receive funding; a dynamic balance is not verified accounting, and mining or payouts were not independently measured here.

The partners section explicitly describes itself as a list of affiliate links, including Trezor, Firefish, Štosuj.cz, 21energy and BTC Prague. Using an offer may support the community, but inclusion is not an independent service recommendation. The page does not establish specific commission amounts or identical terms across partners.

The project site reports a vote from 28.5.2026 to 1.6.2026: 30 votes for and 3 against approved the committee and releasing 100000 CZK for the original artwork competition option. It describes Jednadvacet as an informal network and The Malahar Network, z.s. as the project's legal umbrella. This is the initiative's own account, not a registry check or a mandate to govern the entire Bitcoin community. [Satoshi monument — community board and mandate]
The rules set 1 BTC as the Satoshi Gallery artwork price and a maximum of 1.3 BTC including estimated additional costs. The Prague location remains under discussion. The committee is to decide publicly on unused funds; if the target is missed, funds may go to an original artwork competition and possibly INEV education. Automatic donation refunds are not promised. Final accounting is planned, not a completed financial report verified by this review. [Satoshi monument — fundraising rules]
