For five years, the easiest way to get Bitcoin exposure in a brokerage account was to buy $MSTR. It worked. The stock became a proxy for Bitcoin with leverage on top. But a proxy is not the asset, and the gap between the two is wider than most investors realise. When you buy the stock, you are buying a company. That company carries debt. It issues new shares to fund itself, diluting the holders who came before. It has preferred stock obligations to service. Its shares trade at a premium to the Bitcoin it actually holds, so you are paying more than a dollar for every dollar of Bitcoin underneath. You wanted Bitcoin but you bought a balance sheet, a management team, and a premium. Mining is the other path. The hardware produces Bitcoin from the block reward at a fixed $0.07-0.08/kWh hosting rate. It arrives in your wallet directly, KYC-free, with no company in the middle. No dilution expanding underneath you. No executive deciding when to sell. No premium to overpay on the way in. The deduction comes too. Section 179 lets you write off the hardware in Year 1, and the hosting cost comes off your taxable income every month after. A stock gives you none of that. One path makes you a shareholder in a Bitcoin company. The other makes you the producer, the owner, and the only person with a claim on what comes out. Exposure is not ownership. Mining is ownership.
