TRANSCRIPT OF THE OF DISCUSSION BETWEEN MELISSA LEE AND ADAM BACK, PUBLISHED ON YOUTUBE ON FEBRUARY 23, 2026

Melissa Lee: With us now an exclusive from the iConnections conference in Miami Beach is Adam Back. He’s a co-founder and CEO of Blockstream and known for inventing Hashcash, the system that became the foundation for Bitcoin mining. Adam, great to have you with us.

Adam Back: Thanks for having me on.

Melissa Lee: I want to get your take on what’s going on with Bitcoin. It seems like all of the right things are happening for the Bitcoin story in terms of the legislative sort of arena, the regulatory environment seems to be good for Bitcoin. The investment case is good for Bitcoin in terms of institutional investors coming in. There are all sorts of products tied to Bitcoin. Why is it down so much?

Adam Back: Well, I mean, I think the markets generally have been off based on geopolitical uncertainty and news flow about tariffs and things like that. So Bitcoin has followed that. I think in the short term, Bitcoin follows along. In the long term, it’s de-correlated basically. So I think it’s just a longer term view.

Melissa Lee: Blockstream is a treasury company, correct?

Adam Back: BSTR, Bitcoin Standard Treasury, is a treasury company. Coming up for SPAC approval, we estimate about April. And depending on where the Bitcoin price is, if it holds at this level, that’s actually to our advantage because we go out with a lower reference price and are able to buy more Bitcoin, making our way up the tier that rungs probably number three in the global ranks of Bitcoin Treasury companies by holdings.

Melissa Lee: Why do you think the role is of the Bitcoin Treasury companies and sort of the burgeoning area in terms of how many have come on to the market recently and the decline in Bitcoin prices? Is there any correlation? It seems like that that element of the story is a little bit different in terms of the decline that we’re seeing this time around.

Adam Back: No, I mean, I think they are generally supportive for the Bitcoin price because for the most part they try to hold, buy and accumulate as MicroStrategy started some years ago now. And so they’re effectively taking Bitcoin off the market. They’re generally able to do that in more bullish environments faster. But even today, they’re buying Bitcoin.

Melissa Lee: But even with all these Treasury companies buying Bitcoin, you have these holders that should theoretically provide much more of a floor. Do you think that it does provide more of a floor for Bitcoin as we see prices decline?

Adam Back: I mean, I think Bitcoin tends to be a little weak to the downside because many of the retail investors are end up being all in. And so they don’t have a lot of capital to buy Bitcoin, whereas if you look at public company stocks or big mutual funds, looking at analyst reports, if they see the price of something come down, they might sell some Microsoft and buy some Tesla if they think Tesla is cheaper at a given level. With Bitcoin, most of the investors are all in, so they don’t have that ability to sell something else to reallocate. With more institutional investors coming in, I think you see more of that reallocation between other asset classes, but it also can bring with it some correlation short term.

Melissa Lee: There’s also the new element of being able to bet on the direction of Bitcoin in many different ways, whether it be in the futures market or now the predictions markets. I mean, on Polymarket, you could bet on the direction of Bitcoin in every five minutes. And I’m wondering if that, you think, plays a role in terms of sapping away that retail, even the incremental retail trade, away from actual Bitcoin to other sort of devices and instruments.

Adam Back: I mean, there has been some discussion about so-called paper Bitcoin and derivatives, but I think it’s mostly arbitraged out so that there’s very little effects from paper in Bitcoin. In gold, there’s a lot of synthetic gold. In Bitcoin, it’s either physical or it’s there is side contracts. And there’s very few people that are long-term short Bitcoin. So most of the Bitcoin that’s margin long in like CME futures, there are people doing basis trades who are buying physical Bitcoin to hedge. So I think it mostly offsets, actually.

Adam Back Says BSTR Bitcoin Treasury Firm Will Buy Up to 21,000 BTC

By Oliver Koblizek

Bitcoin may be down sharply this year, but one of the cryptocurrency’s most influential figures sees a major buying opportunity ahead.

In an exclusive interview with CNBC at the iConnections Conference in Miami Beach, Blockstream co-founder and CEO Adam Back revealed that BSTR — the Bitcoin Standard Treasury Company — plans to soon climb the leaderboard of global companies buying Bitcoin.

In the interview, Back said his company would soon be a “top three” Bitcoin treasury company globally, inferring he aims to quickly top Jack Mallers’ Twenty One Capital, which holds 43,000 BTC.

In a comment to BitcoinTreasuries.net, Back stated that his company plans to acquire up to 21,000 additional Bitcoin: “it’s safe to say up to 21k BTC at the current BTC price (subject to regulator approval and depending on spac redemptions).”

The comments come as Bitcoin touched its lowest level in more than three weeks, sitting roughly 25 percent lower since the start of the year and more than 40 percent below its peak from last fall’s rally. Market observers have pointed to geopolitical tensions and tariff concerns as drivers of the broader sell-off, but Back urged a longer-term perspective.

“Markets generally have been off based on geopolitical uncertainty and news flow about tariffs and things like that,” Back explained. “Bitcoin has followed that. In the short term Bitcoin follows along. In the long term it’s decorrelated basically.”

Back’s own company is positioning itself to capitalize on the dip. BSTR, Blockstream’s dedicated Bitcoin treasury vehicle, is advancing toward SPAC approval, which the executive estimated could arrive around April. A lower Bitcoin price at launch would actually benefit the company, he said, because it would allow BSTR to enter the public markets with a reduced reference price and deploy capital to purchase significantly more Bitcoin.

“If it holds at this level, that’s actually to our advantage because we go out with a lower reference price and are able to buy more Bitcoin,” Back noted. The strategy is designed to propel BSTR rapidly up the rankings, targeting a position as the third-largest corporate Bitcoin holder globally by holdings.

Back argued these entities are overwhelmingly supportive of Bitcoin’s price. Following the model pioneered by MicroStrategy years ago, most treasury firms focus on buying and holding rather than trading, effectively removing coins from circulation.

“Even today they’re buying Bitcoin,” he observed. While retail investors often go “all in” and lack dry powder to average down during dips, institutional capital brings greater flexibility to reallocate across asset classes. That dynamic, Back suggested, could eventually provide a firmer floor under Bitcoin even as short-term correlation with traditional markets increases.

He also downplayed concerns about “paper Bitcoin” in futures and prediction markets such as Polymarket, where traders can bet on price moves every five minutes. Back said synthetic exposure is largely arbitraged away, with very few participants maintaining long-term short positions — unlike gold, where paper claims far exceed physical supply.

As BSTR moves closer to its public debut, Back’s message was clear: current weakness is temporary, and disciplined accumulation by well-capitalized treasury companies will continue to strengthen Bitcoin’s foundation.
