When newer people ask me how to start, I tell them three things: first, understand that Bitcoin's four-year cycles have held for sixteen years—this isn't luck, it's embedded in the protocol's halving schedule. Second, don't ask when to buy; ask what percentage of your portfolio you can afford to hold through a 70% drawdown without panic-selling. Third, study 2017 and 2021—not for price targets, but to see how human behavior repeats when fear and greed flip.
