Manifesto

The recently discovered critical Coldcard vulnerability has once again raised an uncomfortable question: how much responsibility are we willing to take on when we decide to hold our own bitcoin?

Some find it absurd to flip a coin or roll dice to build a seed from scratch. We think it's an excellent excuse to put together a gathering with self-custody at its core.

  • 6:00 PM Informal meetup Beers and Bitcoin

FAQ

Admission

Admission is free and open to all, and to attend all you need to do is reserve a spot here.

Do I need to bring a laptop?

It's not required, but it can be handy if you want to take notes or follow along during some of the workshops.

Can I attend just one of the days?

Of course! Just let us know on the registration form.

Will it be streamed?

There will be no streaming. Entropical is designed for all five senses: hands on the materials, dice rolling on the table, conversation with no dropped calls from a bad connection, shared meals, and the sea all around us.

Parking

There's plenty of parking right on Paseo Andrés Segovia (where La Cochera Club is located). Alternatively, there are several nearby open-air parking lots, for example this one.

Accommodation

La Herradura offers lodging options for every taste and budget: camping, shared apartments, hotels… By the event dates it will no longer be high season, so prices will be more affordable. We recommend searching on platforms like Airbnb or Booking.

Language

We're in Spain so most people will be speaking Spanish but all other language speakers are welcome and there will be simultaneous translation of the talks to English.

Who's organizing this
  • Alekqs — Organizer of Málaga 2140
  • Meduzot — Software developer who has contributed to several open-source projects (including some Bitcoin ones)

Manifesto

The recently discovered critical Coldcard vulnerability has once again raised an uncomfortable question: how much responsibility are we willing to take on when we decide to hold our own bitcoin?

Some find it absurd to flip a coin or roll dice to build a seed from scratch. We think it's an excellent excuse to put together a gathering with self-custody at its core.

The entropy that protects your funds matters too much to hand off to a chip, a brand, or a device with a slick design. Self-custody starts before the wallet: it starts with seed generation. Entropical was born to turn the abstraction of bitcoin into something you can touch with your own hands. (And along the way, to strip away the aura of a ritual reserved for engineers in black hoodies.)

Here there will be coins, dice, paper, tests, questions, and the odd discussion with sand between your toes. There will also be games, workshops, and conversations to learn how a seed is generated, what risks exist, which decisions are worth reviewing, and what part of all this anyone can do with a bit of patience.

The goal isn't to pass a test or hand out badges of bitcoiner purity. Entropical is open to anyone with interest and curiosity. Personal freedom is earned by learning to use the tools within our reach. And you learn to use those tools by asking questions, comparing notes, messing up, and starting again.

La Herradura provides the perfect backdrop: the sea, mild weather, an unhurried pace, and a coastline that hasn't been overrun yet. We'll close out the summer sharing a table, with debates on the beach, outdoor activities (kayaking, snorkeling, …), and a few coins tossed in the air.

We invite you to join us from September 18 to 20 to generate entropy on the Tropical Coast.
