Everyone talks about their entry price like it's the number that defines their Bitcoin experience. It isn't.

If you bought 0.1 BTC at $20k and then bought another 0.1 BTC every month through 2022-2023 while the price was between $16k and $25k, your average cost basis is somewhere around $19k. That's not the same as "I bought at $20k." It's actually better — and it changes how you think about what it means to be "up."

The entry price is a moment. Cost basis is a record of behavior.

People who dollar-cost average through volatility often underestimate how much their average has improved over time. They remember the first purchase. They forget the 14 purchases that came after it when the price was lower.

This matters most when the market runs up. If BTC goes to $100k and your cost basis is $31k, you're not "up 5x from my buy at $20k." You're up 3.2x on a much larger position. The actual return on capital deployed is what counts — not the nostalgia number.

The practical fix: track cost basis per purchase, not just your first buy. Most people don't do this until they're filing taxes and suddenly care a lot about FIFO vs HIFO.

Do it before you need to. The numbers will surprise you — usually in a good way.
