For a man who many believe could actually be Satoshi, Blockstream CEO Adam Back is surprisingly understanding on the question of normies buying so-called โpaper Bitcoinโ via the ETFs.
โYou have to have some empathy for the people who want to buy Bitcoin, but they donโt know how to do it, and itโs too complicated,โ Back tells Magazine.
There are limits to his tolerance though. โYou also donโt really want 90% of it in ETFs or something because that might start to become a problem,โ says the London-born, Malta-based cryptographer.
โSo long as thereโs a decent proportion of Bitcoin in individual hands and cold storage by people who are paying attention to what matters for Bitcoin and are going to make a noise if they see something they donโt like, then it should be okay.โ
Being cited in the Bitcoin white paper
The 54-year-old isnโt just any random Bitcoiner. Heโs one of the originals, so much so that Satoshi themself cited Backโs Hashcash in the Bitcoin white paper, published in October 2008, as inspiration for Bitcoinโs proof-of-work system. Back originally developed Hashcash in 1997 to prevent email spam and DoS attacks, and it became the basis of Bitcoinโs mining algorithm.

Satoshi said in the white paper, โTo implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-of-work system similar to Adam Backโs Hashcash [6], rather than newspaper or Usenet posts.โ
He holds a computer science PhD in distributed systems from the University of Exeter and started Blockstream in 2014, which has essentially become a company focused on developing Bitcoin. The firm has its hand in everything from building out the infrastructure around Bitcoin sidechains to dedicating full-time contributors to improving the Bitcoin network.
Blockstream has done some pretty impressive things over the years. In August 2017, Blockstream announced it would use leased satellites to beam the Bitcoin blockchain all over the world so users worldwide could access the networkโs data without having to use centralized internet services.
In October 2018, Blockstream launched Bitcoinโs first sidechain, the Liquid Network, which is a layer-2 scaling solution that allows faster, more confidential Bitcoin transactions.
Bitcoin ETFs make Bitcoin more โreachableโ
It would be easy to wrongly assume that a hardcore Bitcoiner like Back might take issue with ETFs like many other Bitcoin maxis, given the โnot your keys, not your Bitcoinโ mantra.

But Back emphasizes how spot Bitcoin ETFs bolster adoption and make the asset way easier for boomers to buy.
โItโs just accessibility now; now itโs become reachable, they can invest in it,โ Back says.
Back says that ETF investors are typically long-term hodlers anyway.
โETF buyers are sticky; they donโt panic sell. They tend to buy and hold for some years.โ
Many ETF buyers work on the assumption you shouldnโt put money into the stock market if you need it in less than three years.
โIf they use that approach with Bitcoin ETFs, theyโre probably going to do quite well, whereas people who come through Bitcoin exchanges sometimes panic sell,โ he adds.
Lately, some Bitcoin maxis have done a 180 on the ETFs, moving all their Bitcoin into ETFs for convenience and due to the security risks of custodying their own funds. Prominent Bitcoiner PlanB revealed in February that he transferred his entire stash to the dark side.
โNot having to hassle with keys gives me peace of mind. I guess I am not a maxi anymore,โ PlanB said in an X post.

Meanwhile, the other big type of holder who sends shivers down Bitcoin maxisโ spines, governments, โseems to be kind of doneโ with dumping their seized Bitcoin, Back says.
โSome countries sold, you know, 10s of 1,000s of Bitcoin for like, I donโt know, $50 million, and it now would have been like $70 billion or something,โ he laughs.
In July 2024, Germany sold 50,000 BTC for $2.87 billion. While they made a $740-million profit at the time, that would have been $1.98 billion if they had sold at Bitcoinโs current price of $96,053, according to CoinMarketCap data.
Governments around the world currently hold approximately 463,741 BTC โ roughly 2.3% of Bitcoinโs total supply โ according to CoinGecko data.
How annoying is it to be asked if you are Satoshi Nakamoto?
Given Backโs legendary status, itโs no surprise people keep speculating whether Back is Satoshi, a claim he strongly denies, but the bigger question is: How annoying must it be to get asked that every single day?
โIt is okay, you just get used to it,โ Back laughs. โItโs not crazy speculation,โ Back explains, noting that it was just a small group of developers before 2010 who were working on early electronic money systems and designing cryptography.
โSo, yeah, Iโm not, but itโs not a crazy conspiracy.โ
But Back wasnโt actually active in the Bitcoin community until 2013, and by that time, Satoshi had already vanished from the public eye.

โI went and read all the posts on the forum,โ he says, referring to the famous BitcoinTalk forum where Satoshi made their final sign-off post in December 2010. โAt some point, he stops participating.
โWeโre probably never going to know,โ Back says, referring to the mystery of Satoshiโs identity.
โPeople had, like, a decade to look through all that stuff. Look at the headers and the emails, look at the forum, and look for any hints.โ
Back is fine with the idea that Satoshiโs identity will probably never be revealed. โItโs probably a good thing because it makes Bitcoin feel more like a discovery in a commodity than a startup or a company,โ Back says.
Vitalik Buterin is dealing with a โpower struggleโ

And he points out, having a founder or CEO directing operations for a decentralized currency doesnโt make a lot of sense.
โA lot of the altcoins have a CEO and stuff, thatโs weird,โ Back says. He cites Ethereum co-founder Vitalik Buterin, whoโs currently dealing with a โpower struggle,โ as a perfect example.
โHe was like, โIโm in charge,โ Back laughs, adding that misses the entire point of decentralization.
After Ethereum community members rallied behind Danny Ryan at the start of this year to become the new leader of the Ethereum Foundation, Buterin stepped in and said, โThis is not how this game works.โ
โThe person deciding the new EF leadership team is me,โ Buterin said in a Jan. 21 X post. It was surprisingly revealing about how much personal control Buterin still has over the foundation.
You may have picked up on the fact that Back has little patience for any other cryptocurrency besides Bitcoin. โI concluded very early, like 2013, when I got involved, it was a little bit scammy to be making your own coin, also profiteering,โ he says.

โI thought the best thing to do would be to try and help the Bitcoin mission. Either Bitcoin succeeds or nothing succeeds.โ
Blocksize wars conspiracy
Back has faced his share of conspiracy theories. The most outlandish claim heโs come across was during the Blocksize wars, which was a debate about how to improve Bitcoinโs ability to handle more transactions, between 2015 and 2017. While some wanted to increase the block size to allow for more transactions, others didnโt.

โThey wanted big blocks, and some people at Blockstream didnโt, so they constructed a conspiracy about why Blockstream was the evil entity here,โ Back says.
Back explains that, as tensions escalated within the Bitcoin community, someone created a detailed diagram, alleging that Blockstream was secretly funded by some of the worldโs largest financial institutions.
โIt was on a massive piece of paper, with like a string line diagram showing the Bilderberg and Mastercard and AXA and Blockstream,โ Back says.
โAnd actually the Knights of Malta, which is kind of a Sovereign Military Order,โ he adds.

They had โdone some Google researchโ and โmade all kinds of tenuous connections,โ including Blockstreamโs investment from AXA ventures, to come up with the conspiracy.
The divide between supporters of increasing the blocksize and those against it eventually led to a fork and the creation of Bitcoin Cash, which is a version of Bitcoin designed for everyday transactions.

While Back remained loyal to Bitcoin, other early adopters like Roger Ver switched to supporting Bitcoin Cash, leading to ongoing public tension between the two over the years.
Bitcoin must stay decentralized
Bitcoin Cash has gradually reduced in prominence over the years as Bitcoin surged to new heights.
Back says the crucial aspect of the debates over Bitcoinโs future is ensuring it stays true to its ideals.

โWe need to hold on to the decentralized nature of Bitcoin and its permissionless properties,โ he added.
โEveryone wants to scale bitcoin. Itโs really complicated and there is no silver bullet. What weโre trying to figure out is, what is the safe, pragmatic way to do this.โ
Bitcoin price prediction
Back is pretty confident that Bitcoin could hit โa few hundred thousandโ price tag by 2025.

Back points to the FTX bankruptcy as a major catalyst, saying that itโs now wrapped up and theyโll eventually pay out โaround $16 billionโ to investors, which he is confident that most of them will eventually buy back in.
FTX began repaying its โconvenience classโ creditors โ those with claims under $50,000 โ back in February, and the main group of creditors is scheduled to start receiving payments on May 30.
โYou have to buy because the other alternative is you wait for it to fall,โ Back says.
โIf a lot of that gets paid out at once, you might see an effect of that in the market, too,โ he adds.
Back is of the opinion that Bitcoin trading below $100,000 for the last few months is โprobably just a temporary thing.โ
โThe Bitcoin market is kind of reflexive, so if the price jumps, people start buying it and push it up to more,โ he says.
Bitcoin price mindset
Back says all the talk right now about whether Bitcoin can break past $100,000 or if it has already hit its ceiling reminds him of a similar scenario 12 years ago.
โDuring 2013, it went over $100, and I think people were skeptical it would reach the next target like $1,000,โ he says. Then it reached the $1,000 price level, and the cycle repeated once more:
โThen some people were talking about $10,000, and people were saying thatโs crazy.โ
Back says it โsort of seems the same thing again and again, but 10 times bigger.โ
So, knowing everything he knows now and seeing how Bitcoin has all played out, if Back could go back and change just one thing about his Bitcoin journeyโฆit would be just one thing.
โBuying more earlier,โ Back laughs.
