Bitcoin vs Bitcoin ETFs: Why I Prefer IBIT and Its Options
I like Bitcoin as an asset. I just don’t want to hold it as coins. I hold it through spot Bitcoin ETFs, mostly IBIT, because the ETF lets me do what I actually do for a living: sell options with an edge, in a regular brokerage account, with tight bid-ask spreads and odds I can measure.
I’m an options seller with an advantage player’s habits: find the edge, keep the cost of playing low, and never bet so big that one bad run ends the game. Here’s why the ETF side of Bitcoin fits that better than the coins, with the data behind it.
See today’s IBIT covered call strikes. The Covered Call & PMCC Tracker suggests IBIT short calls for the week and about a month out with POP, POT, P50 and IV rank, and keeps your ledger in your browser.

- January 10, 2024: the SEC approved 11 spot Bitcoin ETFs, including BlackRock’s iShares Bitcoin Trust (IBIT), Fidelity’s FBTC, Grayscale’s GBTC, Bitwise’s BITB and ARK 21Shares’ ARKB (SEC, Reuters). Most began trading on January 11, 2024.
- September 20, 2024: the SEC approved Nasdaq ISE’s rule to list options on IBIT. They are American-style and settle in shares.
- November 19, 2024: IBIT options began trading on Nasdaq and traded 353,716 contracts on day one (Nasdaq). Options on several other spot Bitcoin ETFs followed starting the next day (The Block, via SEC filing).
That last date is when Bitcoin became a real options underlying for ordinary US accounts.
Why I hold the ETF instead of the coins
- Options. The main reason. I can sell covered calls, poor man’s covered calls and put credit spreads on IBIT exactly like I do on SPY and QQQ.
- Same account, IRA included. IBIT sits in a regular brokerage account or IRA next to everything else, on one statement and one tax form.
- No wallets, keys or exchange risk. No seed phrase to lose, no exchange to fail, no hack on my own setup. The fund’s custodian holds the coins.
- Simple to size. A share is a fixed slice of Bitcoin (see below), and I size it like any other position.
It’s the same thinking as why I trade indexes instead of single stocks: pick the underlying with the best liquidity and the cleanest rules, then let the edge work.
IBIT options liquidity vs every other Bitcoin ETF
I pulled every option chain for the spot Bitcoin ETFs with listed options from Cboe at the Oct 30, 2026 close and measured the bid-ask spread on the four strikes closest to the price, at the expiration nearest a month out:
| Fund | Contracts traded | Open interest | Expirations | Median spread, ~1 month ATM | % of option price | Fee |
|---|---|---|---|---|---|---|
| IBIT | 1,476,413 | 7,099,068 | 28 | 4¢ | 1.8% | 0.25% |
| FBTC | 2,558 | 87,319 | 13 | 132¢ | 45.1% | 0.25% |
| GBTC | 1,508 | 52,758 | 13 | 98¢ | 37.8% | 1.50% |
| BTC | 644 | 37,576 | 7 | 48¢ | 35.9% | 0.15% |
| ARKB | 183 | 11,960 | 6 | 75¢ | 51.9% | 0.21% |
| BITB | 111 | 9,671 | 5 | 80¢ | 47.7% | 0.20% |
| HODL | 33 | 786 | 4 | 110¢ | 131.7% | 0.20% |
| SPY (for scale) | 14,384,666 | 18,161,399 | 34 | 11¢ | 1.0% | — |
IBIT’s median spread was 4¢, 1.8% of the option’s price. The other funds ran from 36% to 132%. IBIT traded 1,476,413 contracts that day with 7,099,068 open, with 28 expirations including 6 inside a week. The rest of the group together traded 5,037.
In casino terms, the spread is the house edge. Selling a $0.95 call and paying a spread of a cent or two is a game I can beat; paying 40% of the option’s price on the way in and again on the way out is not. That’s why I put my Bitcoin exposure in IBIT even when another fund charges a slightly lower fee.
Where else Bitcoin options trade
IBIT isn’t the only Bitcoin options market. Deribit, an offshore crypto exchange, has long been the biggest venue for options on Bitcoin itself, and CME lists options on Bitcoin futures. One industry tally put Q3 2026 average daily crypto options volume at 28.6% Deribit, 27.6% IBIT and 0.6% CME (Orbit Markets). For a US retail trader, Deribit generally isn’t an option and CME needs a futures-approved account with futures-sized contracts. IBIT puts a deep Bitcoin options market inside an ordinary stock account.
The option strategies I run on IBIT
All examples below use the Cboe quotes at the Oct 30, 2026 close (IBIT at $43.36) and bid/ask mids, with probabilities from the same model as the Covered Call & PMCC Tracker. They’re examples, not recommendations.
| IBIT trade (close $43.36) | Credit / share | POP | POT | P50 | Notes |
|---|---|---|---|---|---|
| Covered call: sell Nov 30, 2026 46 call | $0.95 | 77% | 58% | 87% | 2.2% of the share price, 31 days |
| Covered call, further out: Nov 30, 2026 48 call | $0.50 | 85% | 34% | 92% | 17% chance of being called away |
| Weekly covered call: Nov 6, 2026 44 call | $0.82 | 71% | 81% | 76% | 7 days |
| PMCC short call: Nov 30, 2026 48 call vs a long Jan 19, 2029 35 call | $0.50 | 85% | 34% | 92% | long call mid $18.07, delta 0.81; odds are for the short call |
| Put credit spread: Nov 30, 2026 38/36 | $0.17 | 83% | 34% | 89% | max loss $1.83; short put delta -0.14 |
- Covered calls. Own 100 shares, sell a call above the price. I prefer strikes around 0.20 to 0.30 delta: the Nov 30, 2026 48 call paid $0.50 with a 34% chance of being touched. IBIT’s high implied volatility is what makes the premium worth it.
- Poor man’s covered call (PMCC). Replace the shares with a deep in-the-money LEAPS call, here the Jan 19, 2029 35 call at about 0.81 delta, and sell the same short calls against it. Less capital, but the long call can fall fast in a Bitcoin selloff, so I size it as if it could go to zero.
- Put credit spreads. Defined risk on the downside: the Nov 30, 2026 38/36 put spread collected $0.17 against $1.83 of risk per share. Small credit for the risk, which is why I keep these small (the expected move is my guide).
- The Slingshot. The Slingshot Trade: long-dated options where the premium from selling puts helps pay for upside calls, so I size it for the puts being tested (full write-up). IBIT’s option chain runs out to Jan 19, 2029, which makes it possible.
Before any of these I check the IV rank badge above. High IV rank means fatter premiums and usually a better time to sell.
Bitcoin’s volatility vs the S&P 500
Here’s IBIT against SPY and QQQ from IBIT’s first trading day, Jan 11, 2024, to Oct 29, 2026 (703 trading days, Cboe daily closes):
| Since IBIT’s launch | IBIT | QQQ | SPY |
|---|---|---|---|
| Annualized volatility | 48.4% | 20.8% | 15.4% |
| Days moving more than 3% | 27.0% | 2.7% | 0.7% |
| Days moving more than 5% | 10.2% | 0.4% | 0.3% |
| Opening gaps over 3% | 14.8% | 1.3% | 0.7% |
| Worst day | -14.4% Aug 5, 2024 | -6.2% | -5.9% |
| Deepest drop from a high | -53% | -23% | -19% |
IBIT has been about 3.2× as volatile as SPY. That’s why its options pay so much more, and also why I treat it as a satellite, not a core position. The premium is real, and so are the swings behind it.
The trade-offs of the ETF side
- Fees. IBIT's expense ratio (sponsor fee) is 0.25% a year, taken out of the Bitcoin it holds. Coins in your own wallet have no fund fee (exchange fees apply when you trade).
- Market hours vs 24/7. Bitcoin trades all weekend; IBIT doesn’t. Since launch, IBIT’s average Monday opening gap was 2.4% vs 1.5% on other days, and its worst day (Aug 5, 2024, -14.4%) was a Monday after a weekend selloff. Short options can’t be adjusted while the ETF is closed.
- Someone else holds the keys. The fund’s custodian holds the Bitcoin. You can’t withdraw coins or move them on-chain, and you rely on the sponsor and custodian.
- Early assignment. IBIT options are American-style, so a short call can be assigned before expiration, and a covered call can take your shares.
- Taxes aren’t simpler in every way. Wash-sale rules under Section 1091 cover “stock or securities,” and directly held digital assets aren’t expressly within that scope (Joint Committee on Taxation). How the rule applies to spot Bitcoin ETF shares is less settled, so I don’t plan around it. Ask a tax professional.
How much Bitcoin is in a share of IBIT
From BlackRock’s holdings file, one IBIT share held 0.000566199 BTC as of Oct 29, 2026, about 1,766 shares per Bitcoin. That number shrinks slowly as the fee is paid in Bitcoin. Check it any day on the IBIT Bitcoin per share page, or compare FBTC, GBTC, BTC, BITB and ARKB on the crypto ETF list.
Never blowing up on a volatile asset
- Bitcoin is a satellite. My core income trades are on SPX, SPY and QQQ; IBIT is a smaller slice because it moves about three times as much.
- Defined risk or covered only. Covered calls, PMCCs with a known cost, and spreads. Never naked short options on IBIT.
- Size by the worst case. For a PMCC that’s the whole long call; for a spread it’s the width minus the credit.
- Respect the weekend. I don’t carry large short-dated short options into a weekend.
- Read POT, not just POP. On a volatile asset, getting touched happens a lot; I plan the response before I enter. Here’s POP vs POT vs P50.

FAQ
Is it better to buy Bitcoin or a Bitcoin ETF?
It depends on what you want. Owning coins gives you 24/7 trading and self-custody with no fund fee. A spot Bitcoin ETF such as IBIT trades in a normal brokerage or IRA account, needs no wallet or keys, and has listed options, at a cost of a yearly fee (0.25% for IBIT) and trading only during market hours.
When were spot Bitcoin ETFs approved?
The SEC approved 11 spot Bitcoin ETFs on January 10, 2024, and most, including IBIT, began trading on January 11, 2024. Options on IBIT began trading on Nasdaq on November 19, 2024, and options on several other spot Bitcoin ETFs followed starting the next day.
Why trade IBIT options instead of other Bitcoin ETF options?
Liquidity. At the Oct 30, 2026 close, IBIT’s near-the-money options about a month out had a median bid-ask spread of 4¢ (1.8% of the price), with 1,476,413 contracts traded that day and 7,099,068 open. Every other spot Bitcoin ETF had spreads of tens of cents, often 35% to 50% of the option’s price or more.
Can you sell covered calls on IBIT?
Yes. With 100 shares you can sell a call against them. On Oct 30, 2026, the Nov 30, 2026 46 call paid about $0.95 per share, with POP 77%, POT 58% and P50 87%. The trade-off is that you give up gains above the strike.
What is a poor man’s covered call on IBIT?
It replaces the 100 shares with a long-dated, deep in-the-money call (around 0.80 delta) and sells shorter calls against it. It uses less capital than shares, but the long call can lose value quickly if IBIT falls, so size it as if it could go to zero.
How volatile is IBIT compared with the S&P 500?
Much more. From Jan 11, 2024 to Oct 29, 2026, IBIT’s annualized volatility was 48.4% against 15.4% for SPY, and it moved more than 5% in a day on 10.2% of trading days vs 0.3% for SPY.
Do Bitcoin ETFs gap on Mondays?
Often more than on other days, because Bitcoin keeps trading over the weekend while the ETF doesn’t. Since launch, IBIT’s average Monday opening gap was 2.4%, against 1.5% on other days.
Can I hold a Bitcoin ETF in an IRA?
Generally yes: spot Bitcoin ETFs trade like any exchange-listed fund, so most brokers allow them in IRAs. Options approval in an IRA is usually limited to defined-risk trades such as covered calls, cash-secured puts and spreads; check your broker’s rules.
Is this financial or tax advice?
No. It is education from my own process. Bitcoin and Bitcoin ETFs are highly volatile, options can lose more than the credit collected, and tax treatment depends on your situation.
