I want to recommend some resources to a couple of friends. They are already sold on what the problem Bitcoin solves (kudos to ‘What’s The Problem?’ - Demystifying why we all need Bitcoin), but they want to get deeper now into: wallets, private/public keys, transactions (UTXO, PSBT), software/hardware wallets and signing-devices, ephemeral seed creation, privacy-driven self-custody, blockchain fundamentals (block size, nodes, mining, etc.)…

It does not matter if it is free or paid, as long as the value it provides (consolidating and compressing knowledge delivered efficiently via text/images/video) is worth the price.

Thanks.
