Most Bitcoin writing is built for traders. This one is built for savers. Every week we explain one piece of Bitcoin in plain English, including what it is, how it fits a 401(k) or IRA, and what the trade-offs really are, so you can decide what role, if any, it should play in your retirement. No price predictions. No urgency. We offer free calculators and a plain-English glossary whenever you want to go deeper.
