No signup. No approval. A node can leave, come back and catch up, and the network keeps going.

Every bitcoiner you admire started with a basic question.

Their first sats were few. Their first explanation came from someone patient. 🧡

Most people think the only way to make money in Bitcoin is to buy it.

@RajarshiMaitra quit his fiat job to work on Bitcoin full time. Now @bitshala_org trains Indian developers to do the same.

@LynAldenContact breaks down what's left with @keysopen_doors on the BTC Prague Podcast 👇

Billionaires borrow against their Bitcoin, never sell, and roll the loan forward year after year. It works as long as Bitcoin goes up 30% every year. At BTC Prague, @Bart_Mol of Satoshi Radio explains the strategy, and what happens if you went all in.

Satoshi is gone. The money he left behind isn't going anywhere. Dušan Matuška on what happens if Bitcoin wins: one standard of value, and governments that can't print money to fund wars. Only 21 million. Under 1 million left to mine. Full talk from BTC Prague below.

A physicist ran the numbers on Bitcoin and got one million dollars a coin in about eight years. He does not call it a prediction. He calls it a test. If it fails, his theory fails. Giovanni Santostasi at BTC Prague 2026.
