The Coldcard is, for me, the most secure hardware wallet on the market. It works completely air-gapped, supports multisig and very strong passphrases. In my trainings we build real setups and learn how to protect your seed phrase to the maximum. In follow-up sessions we dive deeper into advanced multisig, PSBT and integration with your own nodes.

The Bitaxe is a fantastic entry into solo mining and shows exactly how Bitcoin mining works. We build it together and connect it directly to your node. In advanced courses we optimize hashrate, cooling, profitability and custom firmware.

BITMAIN Antminers are the workhorses for serious mining. I’ll show you how to run them efficiently and combine them with pools or solo mining. In follow-ups you’ll learn overclocking, power optimization and building small mining farms.

BTCPay Server is my favorite solution for real Bitcoin payments without third parties. We install it on your own server and connect it to Lightning. In deeper trainings we build complex setups with webhooks, ERP integration and automated invoicing.

The Seedsigner is an affordable, open-source signing device that pairs perfectly with the Coldcard. We build it together and use it for secure transactions. In follow-up modules we cover air-gapped workflows, QR code security and multisig with multiple devices.

RaspiBlitz is my go-to full node. It’s stable, Lightning-ready and perfect for beginners. In the courses we build it live. In advanced sessions we professionally configure Lightning channels, watchtowers and backups.

Mempool.space (self-hosted) is the best tool to understand the blockchain in real time. We install your own version. In deeper courses you’ll learn fee optimization, RBF, CPFP and perfect transaction timing.

Bitcoin is not just technology – it is real, hard money. We talk about sound money, stacking strategies and self-custody. In follow-ups we cover taxes, accounting with BTCPay and long-term wealth planning.
