I have a question. Is the mission to produce bitcoin consumers or bitcoin bankers?

I.E. no counterparty risk to my bank whatsoever. Meaning finding an old computer at a thrift store. Buying a new 4T drive. And maxing out that computers Ram.

Then only using is computer to have a Linux / bitcoin core application.

I am my banks IT guy.

I’ve learned from BTC Session, Ministry of nodes and 402.

But I cannot find a step by step video on when the core has a problem. e.g. reindex chainstate.

Is there anything out there?

Thanks.
