Dear SEC Division of Trading and Markets, 

I write as one of the hundreds of thousands of current and previous shareholders of Grayscale® Bitcoin 
Trust (OTCQX: GBTC) who is in favor of approving the Form 19b-4 that NYSE Arca filed with you to 
convert GBTC into a Bitcoin Spot ETF. 
As it stands today, GBTC is trading at a 23.7% discount to its NAV. One of the effects of converting 
GBTC into an ETF is it would allow for shares to be arbitraged by authorized participants through 
simultaneous creations and redemptions. This would cause shares trading at a discount to better reflect 
NAV, and thus protect me, the investor. Currently an investor is being harmed by the GBTC trust not 
being redeemable which is seen in the overall increasing discount to NAV. 
Importantly, earlier this year you also approved several futures-based Bitcoin ETFs. For the reasons 
elaborated on below, I believe that this inconsistency creates an unlevel playing field for Bitcoin ETFs — 
and I strongly believe that the SEC should approve a spot-based Bitcoin ETF, allowing investors, like 
myself, a choice over which product best meets their investment needs. 
To do otherwise would go against the SEC’s core mission of protecting investors like me. 
I support approving GBTC’s conversion to a Spot-Based ETF because it’s consistent with past 
SEC guidance and because it would protect me, the investor 
Previously you chose not to approve Bitcoin Futures ETFs or Bitcoin Spot ETFs like GBTC due to 
concerns about the perceived potential for fraud and manipulation in the Bitcoin markets. In fact, you 
clearly articulated that these concerns could be addressed by demonstrating the following: (1) that the 
underlying Bitcoin market is inherently resistant to fraud and manipulation (or that there are other means 
to prevent fraudulent and manipulative acts and practices); or (2) that a significant amount of trading took 
place on a regulated market (for instance, if the CME-traded Bitcoin futures market were to become the 
leading source of price discovery in the Bitcoin market). [i] It’s important to note that neither of these 
requirements state a preference for Bitcoin Spot ETFs or Bitcoin Futures ETFs. 
Furthermore, as of today, the of pricing of the CME CF Bitcoin Reference Rate (BRR), which is the pricing 
index that CME futures-based ETFs use, is made up of the spot Bitcoin exchanges including Bitstamp, 
Coinbase, Gemini, itBit, and Kraken. (https://www.cmegroup.com/trading/cryptocurrency-indices/cf- 
bitcoin-reference-rate.html) 
Therefore, to the extent the SEC has been and is concerned about fraud and manipulation in pricing of 
the underlying spot Bitcoin markets, that concern would have to permeate across both spot-based and 
futures-based ETFs. 
Since the SEC no longer has concerns with Bitcoin futures ETFs (given trading has begun for these 
products), then it presumably has changed its view about the underlying spot Bitcoin market because 
Bitcoin futures are, by definition, a derivative of the underlying Bitcoin spot market. For this reason, 
whether one, both, or none of these requirements has been met, the SEC should no longer have 
concerns with Bitcoin spot ETFs and should show a similar willingness to permit the trading of Bitcoin 
spot ETFs. 
Spot-based ETFs have proven more efficient and are strongly preferred by investors, as evidenced by 
their commercial success; I believe the same will be true for Bitcoin exposure in an ETF wrapper. For 
example, today investors can gain exposure to gold through both the spot-based SPDR Gold Trust 
(GLD), which is registered under the Securities Act of 1933, or the futures-based Invesco DB Gold Fund(DGL), which is registered under the Investment Company Act of 1940. In its 15 years trading in the U.S. 
public markets, GLD, the largest of all the commodity-based ETFs, has not experienced any material 
investor protection issues and holds $55.5 billion in assets compared to DGL’s $50.4 million (less than 
1% as much). Investors clearly prefer spot-based commodity ETFs over ones that hold futures. 
Lastly, during the period in which the SEC has blocked approval of any Bitcoin ETFs, numerous spot 
Bitcoin investment vehicles have been offered. GBTC, specifically, has amassed more than $28.4 billion 
in assets under management, trades $100s millions daily on OTCQX and is held by hundreds of 
thousands of investors across the country. Furthermore, compared with global commodity ETPs, as of 
[September 30, 2021], GBTC would rank 3rd in assets under management and 3rd in notional trading 
volume. 
In an effort to further protect investors like myself, GBTC has voluntarily registered under the Securities 
Exchange Act of 1934 to subject the fund to the same reporting standards as ETFs. However, because 
GBTC has been unable to register as an ETF, public trading typically occurs at a value that is not 
equivalent to NAV, and as noted above, GBTC has recently been trading at steep discounts to its NAV. 
Permitting futures-based ETFs while simultaneously continuing to deny spot-based ETFs would further 
perpetuate these discounts and clearly go against the SEC’s core mission of protecting investors like me. 
If the SEC is in a position to approve Bitcoin futures ETFs, it should also be in a position to approve 
Bitcoin spot ETFs like GBTC. 
I also support approving GBTC’s conversion to a Spot-Based ETF because of the arguments 
presented under the Administrative Procedure Act 
More recently, Grayscale’s attorneys at Davis Polk filed a letter with you arguing that the approval of 
Bitcoin Futures ETFs but not Bitcoin Spot ETFs, like GBTC, is “arbitrary and capricious,” and therefore a 
potential violation of the Administrative Procedure Act (APA). 
As a shareholder of Grayscale products, I strongly agree with this new argument, as it is reflective of the 
new market dynamics following the approval of several Bitcoin Futures ETFs, and subsequent rejection of 
another Bitcoin Spot ETF application. 
The APA requires federal agencies like the SEC to treat like situations alike absent a reasonable basis for 
different treatment. This means the SEC must treat similarly situated investment products similarly. 
Bitcoin ETF products — Bitcoin futures-based ETFs registered under the ‘40 Act and Bitcoin spot-based 
ETFs registered under the ‘33 Act — are an example of two like situations that should be treated alike. 
Prior to this year, Bitcoin ETF applications were treated alike: You denied both futures-based and spot- 
based ETF applications, citing the potential for fraud and manipulation in the underlying spot Bitcoin 
market. Because both types of ETFs are priced based on the same underlying Bitcoin market, it’s intuitive 
then that you would deny both types of ETFs, given their concerns. 
For example: 
• Today, Bitcoin futures-based ETFs are priced based on exchanges such as Coinbase, Kraken, 
Bitstamp, Gemini, and itBit. 
• Today, Bitcoin spot-based ETF applications, like GBTC, are priced based on exchanges such as 
Coinbase, Kraken, Bitstamp, and LMAX. 
Given the significant overlap, both offerings are therefore alike in the context of Bitcoin ETF approval.As previously noted, earlier this year, your stance on these offerings shifted. While you had approved 
several futures-based ETFs, you have continued to disapprove spot-based ETF applicants – creating an 
example of two like situations not being treated alike – and resulting in an uneven playing field for 
investors like me. 
There have been arguments that the ‘40 Act has more investor protections than the ‘33 Act, and that 
Chicago Mercantile Exchange (CME) Bitcoin Futures are more “regulated” than bitcoin, which makes 
these products not alike in the context of a Bitcoin ETF approval. I do not believe this to be the case in the 
context Bitcoin ETF approvals. 
Regarding the claim that the ‘40 Act has increased investor protections, this law does not address fraud 
or manipulation in the assets or markets of assets that ETFs hold. Instead, the ’40 Act seeks “to remedy 
certain abusive practices in the management of investment companies” (i.e., ETFs), and places certain 
restrictions on ETFs and ETF sponsors. The ‘40 Act even explicitly lists out the types of abuses it seeks 
to prevent, and places certain restrictions on ETFs related to accounting, borrowing, custody, fees, and 
independent boards, among others. Notably, none of these restrictions address an ETF’s underlying 
asset or exchanges on which its pricing is derived (e.g., Coinbase or Kraken). 
Regarding the claim that CME Bitcoin Futures are more “regulated” than bitcoin, I’d note that in each of 
the SEC’s previous spot-based Bitcoin ETF denials (including the latest), you counterintuitively stated that 
the CME Bitcoin Futures market is not “significant” enough to grant approval. What this implies is that 
someone could, in theory, manipulate bitcoin on a spot exchange and have it impact the regulated CME 
Bitcoin Futures and, therefore, the futures-based ETF too. (Again, assuming you believe fraud or 
manipulation exists in the first place). Notably, again, the ‘40 Act doesn’t address this concern either. 
As it stands, the Bitcoin ETF landscape is unfair and discriminatory against GBTC shareholders like 
myself, and all of the other U.S. investors looking for an accessible and efficient way to gain their Bitcoin 
exposure. 
While I certainly commend the efforts made toward approving the first Bitcoin Futures ETFs, as a GBTC 
shareholder, I also strongly encourage you to continue to fulfill your mandate of protecting investors, while 
promoting open, competitive markets, by approving GBTC as a Bitcoin Spot ETF. 



Thank you for your time
