MicroStrategy — rebranded as Strategy in 2025, though its ticker is still MSTR — is the world's largest Bitcoin treasury, with more than 800,000 BTC on its balance sheet. Its stock is by far the most popular way to get Bitcoin exposure through the market, and it's perfectly accessible. Here's how.
Where MSTR trades
MSTR trades on the Nasdaq (United States). That's good news: practically any broker with US market access offers it, without the barriers that affect US spot Bitcoin ETFs for the EU retail investor.
Brokers where to buy MSTR
You have plenty of choice: Interactive Brokers (the most complete, with the lowest fees for the US market), DEGIRO, Trade Republic, eToro, Trading 212, Revolut, XTB and others. For a buy-and-hold position, the per-trade fee matters little; for recurring contributions, check whether the broker offers automatic savings plans. Always verify the current fee and the currency conversion (your base currency / USD) before trading.
How it's taxed
How gains are taxed depends on your country of residence — in most jurisdictions, selling MSTR is a capital-gains event. If you use a broker domiciled abroad, bear in mind it often doesn't withhold or report automatically to your tax authority, so you may need to declare manually. Check your local rules or a tax advisor.
What you're buying (and the risks)
MSTR is not Bitcoin: it's the stock of a company that accumulates Bitcoin with financial engineering (convertible debt and equity raises). It trades with an mNAV — a premium or discount over the Bitcoin backing each share — and works as leveraged exposure: it tends to rise more than BTC in up legs and fall more in corrections. Add to that management-team risk and debt-structure risk. It's a higher-risk, higher-potential tool than holding spot BTC.
Alternatives and how to compare it
