Grayscale Bitcoin Mini Trust ETF
Grayscale’s lower-fee answer to the post-approval bitcoin ETF market.
$10,000 invested, compounded for 30 years.
Compound-fee impact at an assumed 8% annual return. The expense-ratio benchmarks (lowest + category median) come from the live cohort in /compare/etfs; the 8% return is illustrative, not a forecast.
The full custody chain.
When you buy BTCshares, you don't hold Bitcoin — you hold a claim on the trust. The trust holds a claim on the custodian. The custodian holds the actual keys.

Questions readers actually ask about BTC.
Is owning BTC the same as owning Bitcoin?
Functionally for most purposes, yes — you get price exposure backed 1:1 by BTC held in cold storage. Mechanically, no — you own shares in a trust, not the underlying Bitcoin. The difference matters in three scenarios: (1) self-custody control, (2) using BTC as collateral elsewhere, (3) keeping access if your brokerage fails.
Does BTC pay dividends?
No. The trust holds Bitcoin, which doesn't generate yield. All returns come from price appreciation of the underlying.
What happens to my BTC if Grayscale fails?
The Bitcoin backing BTC is held by Coinbase Custody Trust Company as a qualified custodian, legally separate from Grayscale's operating funds. The trust's assets would not be claimable by Grayscale's creditors.
Can I buy BTC in my 401(k)?
Depends on your plan. Most modern plans that allow individual brokerage windows support it. Many default 401(k) menus don't.
