When spot BTC ETFs went live in the US back in January, it wasn’t yet clear how they would perform, but there was a sense that their launch was an occurrence that–if not exactly inevitable–had been likely to occur at some point.

In the case, though, of spot ETH ETFs, which went into operation last Tuesday, it feels in some ways like a different story. Approval from the SEC came through in May, but that decision surprised many observers and even prompted speculation that there could have been political motivations at work, since presidential candidate Donald Trump was at that time in the process of establishing a publicly pro-crypto campaign stance.

From there, it didn’t take long to get to launch, and while 2024 is becoming a year that will be remembered for its crypto ETF developments (don’t forget that two firms–VanEck and 21Shares–have also filed applications with the SEC for spot SOL ETFs), it’s becoming apparent that along with similarities between the BTC and ETF products, there are also some key differences.

That in mind, let’s take a look at those similarities and differences, and the implications for the products, their underlying assets, and the rest of the crypto space.

How Are the BTC and ETH ETFs Similar?

In the US, there have been ongoing disagreements, mainly between the SEC and almost the entire crypto industry, about whether or not the majority of crypto tokens can be classified as securities and therefore fall under the purview of the SEC. What’s notable is that the SEC appears to want crypto tokens within its remit, and so often argues the case for coins as securities, with a few exceptions.

Most obviously, the commission accepts that BTC is best placed in the commodities category, and–although Chair Gary Gensler has been equivocal on the matter–the widespread consensus appears now to be that ETH also can be accepted as a commodity.

And in fact, as far back as 2018, then-director of the SEC’s Commission of Corporate Finance William Hinman expressed the opinion that ETH, like BTC, was decentralized enough to be treated as a commodity rather than a security. Also, in 2023, CFTC Chair Rostin Behnam explained in reference to ETH futures funds that,

“We would not have allowed the Ether futures product to be listed on a CFTC exchange if we did not feel strongly that it was a commodity asset”.

Another similarity between the BTC and ETH funds lies in how they are affected by Grayscale. In short, prior to spot BTC and ETH ETFs, Grayscale already ran BTC and ETH trusts, both of which have now been converted to ETFs. However, neither of the converted funds has fees set to be competitive with newcomer ETFs from other firms, and major outflows have occurred from the BTC product, with the same process appearing now to be happening with the ETH product.

The new BTC ETFs had such strong, sustained inflows that they have been able to thrive despite the Grayscale overhang, but it remains to be seen whether the ETH products can also produce the demand necessary to immediately offset any short-term Grayscale outflows, should they continue to occur.

Finally, for another similarity we can look at way Bitcoin is being publicly praised by BlackRock CEO Larry Fink, while at the same time BlackRock’s tokenized treasuries fund, BUIDL, runs on the Ethereum blockchain. To long-term crypto users–who have weathered countless criticisms and dismissals through the years from establishment sources–this is a rapid turn of events, but it’s telling that Fink and BlackRock currently reserve the lengths of their crypto asset adoption to BTC and ETH.

How Are the BTC and ETH ETFs Different?

One area in which the ETFs differ from one another is around the narratives driving interest in their respective underlying assets. Bitcoin, at the moment, is frequently promoted as a store of value that can be regarded–as Larry Fink has stated–as digital gold, and which also, for example in El Salvador, can be a working currency. Ethereum, on the other hand, was described in a recent BlackRock ETH ETF promotional video as “a global platform for applications that run without decentralized intermediaries”, and the same video directly contrasts BTC’s “scarcity” with ETH’s “utility”.

Finally, one more notable difference stems from the fact that Bitcoin has no identifiable founder. As such, its most prominent advocates operate as adopters leading by example rather than as technicians, meaning we have persuasive individuals such as MicroStrategy Executive Chairman Michael Saylor, President of El Salvador Nayib Bukele, and now also BlackRock’s Larry Fink making the public case for BTC. And this, again, makes it a little more like gold, which also, after all, has no CEO explaining his invention on the media circuit.

ETH, on the other hand, has, in Vitalik Buterin, a famous and still-active co-founder regarded as a figurehead for the blockchain, and this sometimes results in misunderstandings: investors from a traditional business and finance background may wonder why Buterin is not in the spotlight promoting ETH now that the ETFs are freshly launched, while to crypto-natives this sounds strange: Ethereum is a decentralized network and, according to a common kind of crypto ethos, should always be moving away from hierarchical leadership.

“Isn’t it bizarre that Vitalik is not on Bloomberg or CNBC explaining what Ethereum is? Does he even care? Have you ever seen this during an IPO when the company is not running some form of awareness?”

But if it’s not Vitalik Buterin’s job to promote ETH (just as it’s not the job of pseudonymous and long-absent Bitcoin creator Satoshi Nakamoto to promote BTC), then who, if anyone, should be doing that job? Does Ethereum need a Michael Saylor-type figure pushing its value proposition and also taking the bet in real time? That depends on who you ask, and perhaps ETF issuers–as through the above-mentioned BlackRock video–will take up the task, or alternatively, perhaps crypto will always operate by its own novel conventions, and traditional finance will adapt accordingly.
