B-Café

B-Café
Where Bitcoin becomes concrete, human, and local.
Who I am
Adam Back         and                me
Copinmalin
Project Manager in my « fiat job, » but Bitcoin has become much more than a hobby.
My journey: discovered crypto in 2017 during the ICO wave. Quick disillusionment, then in-depth research led me to the revelation: Bitcoin.
I fell down the rabbit hole and decided to take concrete action for this technology that changes everything.
My Involvement in the Bitcoin Ecosystem
Regular Meetups
Organized with Rogzy: 20 to 50 people every two weeks to exchange and learn.
AlpineChain Association
Creation and animation of a community of 300+ passionate members.
B-Only Conference
150 participants, 3 days of discussions with key French-speaking actors.
National Coordination
Leading the 54 Bitcoin Meetup France communities with Profedustream and PlanB to unite the ecosystem.
Technical Translation
Contribution to the BitcoinOps newsletter in French, an essential resource for Bitcoin Core developers.
PlanB BizSchool Academy
One of the 21 winners of the 2024 edition
The Trigger
« The desire to do more for the community, to leave fiat behind and embrace the long-term vision of Bitcoin. »
The idea was validated at home – good advice often comes from our wives.
Inspired by the trend of concept store cafes and new collaborative workspaces, I wanted to create something unique.
Objective: a Bitcoin-only place, both welcoming, educational, and lively, where technology becomes human.
The Problem
Bitcoin remains abstract
For the general public, Bitcoin remains technical and intimidating. Jargon and complexity hinder adoption.
Merchants unprepared
Merchants don’t know how to concretely integrate Bitcoin into their daily operations.
Dispersed communities
Communities are active but lack a physical anchor or a strong unifying brand.
There is a missing bridge between curiosity and real usage.
The Solution: B-Café
A hybrid Bitcoin-only space: café, coworking, education, and community.
Welcoming Hub
A welcoming space for bitcoiners, digital nomads, and anyone looking for an inspiring environment.
Accessible Gateway
A barrier-free first contact with Bitcoin for the curious and the general public who want to understand it.
Engaging Education
Workshops, events, and training to learn, exchange, and grow together in a supportive environment.
Value Proposition
B-Café targets four distinct audiences, offering tailored benefits to each.
General Public
Understand Bitcoin simply, without jargon or intimidation. A human approach that demystifies the technology.
Merchants
Receive step-by-step guidance to accept Bitcoin payments: training, tools, technical support.
Bitcoin Ecosystem
A local anchor, a living showcase to unite the community and embody the network’s values.
