What if you'd bought the other one?
Punch in your position and see the road not taken — what the same dollars in the other asset would be worth today, tracked from your purchase date to now.
MSTR would have left you $321 richer than BTC — a 15% difference on the same money.

Or dollar-cost average instead
A lump sum bets everything on one entry date. Dollar-cost averaging spreads the same idea across many buys — a fixed amount every week or month — so your result depends less on timing. Here's how the same recurring buy would have played out in bitcoin versus MSTR.

Frequently asked
Should I buy MSTR or Bitcoin?+
This tool doesn't give advice — it shows history. Bitcoin is the underlying asset; MSTR is a leveraged, actively-managed bet on it that can trade at a large premium or discount to the bitcoin it owns. In past bull markets MSTR has outrun BTC, and in drawdowns it has fallen harder. Run your own dates above and see how the two compare for the period you care about before deciding.
How is the 'what if' result calculated?+
We convert your dollars into a quantity of each asset using the daily closing price, then multiply by today's live price. When your chosen date falls on a weekend or market holiday, we use the most recent prior Nasdaq trading-day close for MSTR and Bitcoin's close from that same effective date — never a future price. BTC trades every day, so its price is always exact-day unless the effective date is shifted to match MSTR's last trading session.
Does it include dividends, fees, or taxes?+
No. The result is price return only. It ignores trading fees, taxes, and any preferred-stock or dividend income. Real-world outcomes would be lower after costs.
Why does MSTR sometimes beat Bitcoin and sometimes lose to it?+
Leverage and premium. Strategy funds bitcoin buys with debt and stock sold at a premium, so each dollar of BTC gain can become more than a dollar of MSTR value in bull runs — and the same mechanics amplify losses in drawdowns. That's why the winner flips depending on the start date you pick.
What purchase date should I use?+
Use your actual entry date for a personal answer, or try the preset buttons (Aug '20 marks the start of Strategy's bitcoin strategy) to compare full market cycles. MSTR history before August 2020 predates the bitcoin treasury and isn't a like-for-like comparison.
