The CEO of Swedish Bitcoin treasury company H100 just put his own money on the line, buying over 400,000 shares while the firm’s balance sheet holds firm at 3,506 Bitcoin — the latest sign that European executives are still betting big on a corporate Bitcoin strategy even after a rough summer for prices.

The Hook: Insider Buying at a Bitcoin Treasury Firm
In a September 17 primary-insider disclosure, H100 Group revealed that CEO Eirik Grøttum increased his exposure to the company through purchases totaling 407,163 shares for 621,887 Swedish krona — roughly 55,000 USD — at an average price of SEK 1.53 per share. The buying was carried out through Kode Oslo AS, a closely associated company where Grøttum sits on the board, owns 20 percent, and helps steer investment decisions.
Most of the purchase — 405,663 shares — happened on September 15, with a smaller 1,500-share buy dating back to August 19. Following the transactions, companies associated with Grøttum collectively hold 5,399,464 H100 shares. One crucial clarification: this is a stock purchase by the CEO, not a new Bitcoin purchase by the company. H100’s treasury stands unchanged at 3,506.4 BTC.
On-Chain Evidence: How H100 Got to 3,506 Bitcoin
H100’s Bitcoin position tells one of the more unusual corporate-treasury stories in Europe. The company, which describes itself as a technology firm serving health and longevity providers alongside its treasury strategy, started small: its first purchase in May 2025 was just 4.39 BTC. By June 30, 2026, it held 1,051.03 BTC.
Then came the leap. On August 10, H100 completed its acquisition of NSD AS, which held Moonshot AS and PDI AS, bringing 2,455.37 BTC into the group and nearly tripling the treasury to 3,506.4 BTC. No cash changed hands. H100 issued 790,534,666 new shares to the sellers at SEK 1.86 each — consideration of roughly SEK 1.47 billion. The new shares represented about 70 percent of the company after closing, leaving seller Geir Harald Hansen with a controlling stake of approximately 69.2 percent. H100 calls it the largest M&A deal ever completed in European public Bitcoin equity and the first public-market acquisition done Bitcoin-for-Bitcoin — company claims that were not independently verified across the sector.
The deal’s valuation used Bitcoin at SEK 598,926.69, roughly 62,900 USD, based on the Coinbase BTC/SEK spot price at a July 31 reference time — a benchmark, not a market purchase price. Today Bitcoin trades around 76,600 USD, meaning the acquired stack has appreciated meaningfully since the deal was struck.
The Core Conflict: Skin in the Game vs. a Stock That Tracks Bitcoin
Why does insider buying matter here? H100 is one of a growing class of public companies whose equity is effectively a leveraged bet on Bitcoin. Its reported earnings swing with crypto prices — the second-quarter report showed the treasury’s mark-to-market effects front and center. When a CEO buys shares, he is not just signaling confidence in the business; he is personally buying Bitcoin exposure through the one vehicle he knows best.
Grøttum is also a relatively new chief executive. He took over on August 11 — one day after the Norwegian acquisition closed — having previously run Moonshot AS, where he worked with H100 Chief Investment Officer Peter C. Warren managing Bitcoin holdings belonging to Geir Harald Hansen. His background spans software development, quantitative trading, asset management, and fintech. His predecessor, Johannes Wiik, moved into the chief operating officer seat. The insider purchase, disclosed through proper regulated channels, is the new CEO’s first high-profile vote of confidence.
The counterargument is structural: with about 70 percent of shares issued to a single controlling seller and the stock tightly coupled to Bitcoin’s price, minority investors carry governance and concentration risks that plain Bitcoin ownership does not have.
Market Implications: What It Means for Your Wallet
For most retail investors, H100 itself is a niche, small-cap Swedish listing. But the pattern it represents matters. Corporate treasuries — from giants like Strategy to smaller European players like H100 and MARA, which recently bought back 1,292 BTC — are collectively a structural source of Bitcoin demand. Every company that holds and grows a BTC treasury removes coins from circulation and adds a persistent, price-insensitive buyer class to the market.
Insider buying adds a second, softer signal: executives closest to these balance sheets are choosing equity over cash at current prices. That is never a guarantee — insiders can be wrong, and concentrated small-caps can be brutal on the way down — but it is data. If you hold Bitcoin directly, the trend is a tailwind. If you are tempted by treasury-company stocks instead of Bitcoin itself, H100 is a good reminder to check the fine print: share dilution, controlling shareholders, and fee structures all sit between you and the coins.
The Verdict
H100’s story is a European echo of the corporate Bitcoin treasury wave: modest beginnings, an aggressive all-share acquisition, and now a CEO buying in with his own krona. The 3,506 BTC treasury remains intact, the new leadership has deep Bitcoin-native credentials, and the insider purchase signals alignment. For regular investors, the lesson is not necessarily to buy H100 — it is to recognize that companies, executives, and their personal wallets are increasingly voting for Bitcoin as a reserve asset, even at 76,600 USD a coin.

SEK 1.53 average entry and 3,506 BTC on the books. small cap treasury plays are the only place insider buying still means anything, the big players just issue shares at whoever
insider buying means something at SEK 1.53, agreed, but 55k USD is pocket change for a CEO. the 3,506 BTC on the books is doing the heavy lifting here, not his buy
55k is pocket change for a nasdaq ceo, but grøttum runs a small swedish miner. relative to what that job actually pays, its real skin
55k of stock for a ceo running a 3,506 BTC treasury is pocket change, but buying through Kode Oslo where he owns 20% is a weird flex. just buy on your own name my guy
SEK 1.53 avg is basically a lottery ticket at this point. still, real money is real money
buying through kode oslo is disclosure arbitrage, plain and simple. if he wanted the clean signal hed buy on market like the rest of us
arbitrage implies he gained something. the disclosure threshold rules made him file within days either way, buying through kode oslo just spreads his exposure
the swedish rules cap the delay at days, not weeks, kode oslo or not. structured exposure is not arbitrage
buying through kode oslo lets him delay the disclosure until the threshold actually hits. not saying its shady, but its not the clean signal people want it to be
threshold disclosure is literally how the swedish rulebook works. he filed the moment he had to. calling it arbitrage is a stretch
55k is pocket change but the 20 percent kode oslo stake is doing the talking. aligned either way, just not the clean retail signal people want it to be
The 20 percent Kode Oslo stake is the real tell here. He is effectively averaging into his own associated vehicle, and retail reading it as a personal endorsement are doing the marketing for free.
kode oslo point is fair but hes still buying with actual cash instead of options grants. in small caps that distinction actually matters
grottum buying 407,163 shares of his own company near the lows. either conviction or a very expensive apology for the summer
3,506 btc held through the drawdown plus insider buying. compare that to the firms that paper handed at the bottom lmao
the firms that paper handed at the bottom sold into the exact tape grottum was buying. thats the whole asymmetry right there
this. the sold-into-the-low crowd is quiet today. 3,506 btc untouched through the summer says more than any filing
an expensive apology would be buying at the top. he averaged in near the lows, so its conviction. boring answer i know
everyone dunked on the swedish treasury strategy after the summer dump and now Grøttum is averaging down. respect, most execs just quietly vest and dump
nobody covers H100 because its not us listed. swedish treasury cohort quietly doing the microstrategy playbook on a budget
3,506 btc on a swedish small cap balance sheet is not a budget microstrategy, its a leveraged bet with a stockholm listing. different risk entirely
SEK 1.53 avg while the NSD deal papered at 1.86 a share. he is buying his own acquisition discount, thats the part nobody mentions
buying the discount only pays if the close lands. NSD falls through and that 1.53 entry stops looking like conviction real fast
Buying at 1.53 against a 1.86 deal price only works if the NSD close actually happens. That spread is a merger arb position, and those go to zero on one regulator letter.
405,663 of the 407k shares landed on september 15 in one print. thats not averaging in, thats a statement at SEK 1.53
407k shares bought while btc sat under water all summer. this was no victory lap buy, thats the detail that sticks out to me
407k shares is a friday lunch order for a nasdaq ceo but for a small swedish btc miner its a real chunk of his net worth. context is everything with insider buys
