Bitcoin: What Happens When You Invest $100 Every Month for Over a Decade?

Starting in 2015, putting $100 into Bitcoin each month would have turned $13, 700 into over $632, 000 by mid-2026. That’s a massive 4, 515% return. But here’s the catch: this strategy didn’t make anyone rich overnight. Prices swung wildly, and at one point, the total investment lost 76% of its value during the 2022 crash. Even with steady purchases, holding through those drops would have tested anyone’s patience.What if someone started later? For those who began in May 2021, right before Bitcoin’s big drop, the same $100-a-month plan still grew their money—just not as dramatically. Over five years, that $6, 100 turned into around $11, 244, beating a lump-sum investment made at the same time. But here’s the twist: over shorter periods, dumping all the cash in at once usually worked better. Time and timing both matter. Most people assume dollar-cost averaging (DCA) is the safest way to invest. But the data shows it’s not always the best choice. Even with regular buys, investors still faced brutal losses. The real lesson? Bitcoin’s long-term growth is impressive, but its ups and downs can break weaker hands. Hindsight makes success look easy—but riding out crashes is harder than charts suggest.
