Bitcoin rally could revive treasury buying, but easy-money days over

Corporate Bitcoin purchases could accelerate toward the end of 2026 and into 2027 if the cryptocurrency rallies, but investors are likely to be more selective about which treasury companies they finance, according to analysts. Speaking to Cointelegraph, Bitwise head of research Ryan Rasmussen said there was a broad slowdown in Bitcoin treasury buying in Q3. Strategy’s Bitcoin holdings increased by a net 1,666 BTC in Q3, down from 83,901 BTC in Q2, according to company filings. Other public companies added a net 5,617 BTC, compared with 45,725 BTC in the previous quarter, according to figures supplied by Rasmussen. Rasmussen said he expects a re-acceleration of corporate Bitcoin purchases to begin as early as this year. Bitfinex head of derivatives Jag Kooner said renewed buying could follow if treasury companies regain premiums to the value of their Bitcoin holdings, allowing them to issue shares and acquire more Bitcoin without diluting existing shareholders’ Bitcoin exposure per share. The model became popular during the 2025 treasury boom, when companies could raise capital by issuing shares at a premium to the value of their Bitcoin holdings. But as those premiums narrowed or disappeared, issuing new shares became less attractive, limiting companies’ ability to finance additional purchases. “Shareholders have seen premiums collapse and some companies sell into weakness. Investors are now pricing these businesses on funding costs, balance-sheet discipline and bitcoin per share,” said Kooner. “A rally could therefore restart buying, particularly among companies with credible financing structures but a return to last year’s indiscriminate capital raising looks unlikely.”Established Bitcoin treasuries may get first access to capital Bitwise’s October market report also showed a decline in the number of Bitcoin treasuries in Q3, driven by smaller companies abandoning their Bitcoin treasury strategies. A dozen companies that entered during the 2025 treasury boom sold their entire holdings mostly to repay debt or return cash to shareholders after their stock premiums evaporated, said Rasmussen.Kooner expects established players to attract capital first if buying resumes.“Initially, capital would likely gravitate towards established players, which have the scale, the liquidity in their own securities and the track record investors now demand,” he said. Related: Bitcoin is rejected at $83K as US bond yields reverse higher with equitiesRasmussen said most of the largest corporate buyers outside Strategy were operating businesses adding Bitcoin from cash flow rather than issuing stock to fund purchases. That represents “a smaller source of demand but a healthier one,” he said.Meanwhile, Kooner cautioned that a broader resurgence of new treasury-companies could emerge only after a rally is well underway.“A broad wave of new listings would most likely arrive late in a rally, once premiums have widened and that timing is itself a warning sign.”Bitcoin ETFs could support recovery without treasury boom Even without another corporate Bitcoin buying boom, Rasmussen said there will be other drivers for a Bitcoin recovery, pointing to $6.4 billion in spot Bitcoin net inflow in Q3. “Corporate purchases are one source of demand for bitcoin, but not the only source,” he said.Kooner agreed ETF demand could sustain the recovery for a period, but cautioned that some activity reflects basis trades that can unwind quickly.“Without corporate buying, the market loses a price-insensitive bid and becomes more dependent on allocators who rebalance with macro conditions,” he said.Recent flows show that ETF demand can reverse. US spot Bitcoin ETFs recorded around $229 million in net outflows last week, their second consecutive week of net withdrawals, according to SoSoValue data.Magazine: Made an ‘honest’ mistake with crypto taxes?

South Korea to meet crypto exchanges amid calls for tax delay

South Korea’s senior finance officials are reportedly set to meet crypto exchanges on Tuesday as calls to postpone a planned cryptocurrency tax are heating up ahead of its scheduled implementation in January. According to Yonhap, the government is planning to hold a consultation on crypto taxation, with representatives coming from Upbit, Bithumb, Coinone, DigitalX and Gopax, along with executives of the Digital Asset Exchange Alliance, known as DAXA.Government officials attending include Kwon Dae-young, first vice minister of finance and economy, and Yoo Young-jun, director general for digital financial policy at the Financial Services Commission.South Korean regulators have delayed the crypto tax three times, with the latest delay pushing the start date to 2027 amid political disagreement and industry pushback over exchange readiness and the threshold level. An exchange official told Yonhap on Sunday that unresolved transaction rules and limited time to prepare infrastructure supported postponing the tax. “Standards for different transaction types have not yet been finalized, and time is running short for practical preparations on the infrastructure side,” an exchange official told Yonhap. “There is a shared view in favor of postponing the start of taxation.”On Friday, Democratic Party of Korea lawmaker Park Min-gyu introduced a bill seeking to postpone the tax until Jan. 1 of the second year after South Korea begins sharing data under OECD’s Crypto-Asset Reporting Framework (CARF). With the first exchange expected in 2027, taxation would begin in 2029.Related: South Korea plans cybersecurity overhaul after attacks hit banks, crypto firmsCointelegraph is committed to independent, transparent journalism.

Qubic freezes chain after attacker drains 1.4K wallets with weak seeds

Layer-1 blockchain network Qubic halted operations Sunday after an attacker reportedly exploited weakly generated wallet seeds to drain approximately $1.4 million from more than 1,400 accounts, according to the project. In a statement on X, Qubic said the network was halted at tick 85,371,949, where it remains paused at the time of writing. Qubic said the vulnerability affected wallet seeds generated using any browser on an iPhone or iPad, Safari on a Mac until Oct. 18, 2026, or the Qubic iOS app before July 2025, leading to 2.94 trillion Qubit (QU) stolen. “87.1% of the drained funds never left the Qubic network and remain frozen in place,” said Qubic. “The remaining 12.9% was sent to MEXC, whose team froze the receiving account within about an hour.” The Qubic theft is the latest in a series of attacks tied to weak wallet seeds. In July, Coldcard disclosed that attackers had stolen funds from wallets whose seeds were weakened by a firmware bug. Similar flaws affected Trust Wallet’s browser extension and the Libbitcoin Explorer tool in 2023.Related: Bitget’s $388M hack pushes Q3 crypto security losses past $1BQubic said it has fixed the seed-generation flaw in the latest version of its web wallet. A GitHub commit for version 4.26.4 shows that Qubic replaced JavaScript’s Math.random() function, which is not suitable for generating cryptographic secrets, with the cryptographically secure crypto.getRandomValues() function when creating wallet seeds. Qubic said its core team is identifying affected wallets and preparing recovery options for a vote by the network’s Computors, which will decide what happens to the frozen funds. The team said it would publish a full technical report after a recovery plan is settled. It has not announced when the network will restart.Qubic did not immediately respond to Cointelegraph’s request for comment. Qubic is a layer-1 blockchain that supports transactions and smart contracts without fees. It is built on Useful Proof of Work (UPoW) – a consensus mechanism that repurposes mining energy to train artificial intelligence. Qubic’s token had a market capitalization of about $62.6 million at the time of writing, according to CoinGecko.In the third quarter, hacks and exploits accounted for 19% of crypto crime cases but 40% of reported losses, according to AMLBot’s 2026 investigations report, which looked at 250 investigations it opened since the start of the year. Magazine: Richard Heart caught ‘off-guard,’ QDay gets even closer: Hodler’s Digest
