Which one actually won?
Put the same money into Bitcoin, Apple and S&P 500 in the same year and watch them pull apart. Same start, same amount — the only difference is what you picked. Add or swap assets, change the year, and find the winner.
A side-by-side what-if is the fairest way to see the cost of a guess. The same dollars, committed on the same day, end up worlds apart depending only on what you bought — that gap is the whole story of picking winners versus owning the market. Switch to a bit each year to see how steady buying narrows (or widens) the spread, then open any asset on its own to go deeper.
