Did Someone Really Break Bitcoin’s Encryption? Here’s The Truth About What Happened
The latest threat to Bitcoin’s cryptography is quantum computing. A researcher called Giancarlo Lelli has now won a one Bitcoin prize for using quantum hardware to crack a small cryptographic key linked to the same family of mathematics that protects Bitcoin. This sounds terrifying at first glance, as it threatens the future of billions worth of Bitcoin. However, it also needs careful handling, because the truth is more complicated than breaking Bitcoin’s encryption. Researcher Makes Successful Attack On Elliptic Curve Cryptography The event came from Project Eleven’s Q-Day Prize, which was awarded to independent researcher Giancarlo Lelli. Lelli used publicly available quantum hardware to break a 15-bit elliptic curve cryptography key, using a variant of Shor’s algorithm to derive a private key from a public one. The previous public quantum attack record was a 6-bit cryptographic key in September 2025, which means Lelli’s 15-bit result extends the record by a factor of 512 in complexity. Interestingly, the hardware involved was not a classified government system or a private supercomputer. Lelli ran the attack on a publicly accessible quantum device with about 70 qubits, completing it in only 45 minutes. The implications tie directly into how BTC’s security model is structured. That matters because Bitcoin relies on the same elliptic curve cryptography that was broken. According to Project Eleven, an estimated 6.9 million BTC valued at about $520 billion, are held in addresses where the public keys have already been revealed on-chain. This includes the roughly 1.1 million BTC attributed to Bitcoin creator Satoshi Nakamoto. Advances like these raise concerns about how soon such holdings could become vulnerable, bringing forward timelines to when they can be under threat from bad actors. Is Bitcoin’s Encryption Broken? A 512x jump in seven months is the kind of progress curve that tends to get people’s attention. Progress at that pace suggests the computational threshold required to challenge BTC may be very close. However, Bitcoin does not use 15-bit keys. Bitcoin’s real security operates at a 256-bit scale, which is vastly beyond what was broken in this experiment. Project Eleven CEO Alex Pruden noted that “The resource requirements for this type of attack keep dropping, and the barrier to running it in practice is dropping with them.” Still, theoretical resource estimates for a full 256-bit attack have fallen massively over the past year. Google’s April 2026 whitepaper put the requirement at under 500,000 physical qubits. A subsequent paper from Caltech and Oratomic brought that figure as low as 10,000 qubits in a neutral-atom architecture. The quantum threat does not mean every Bitcoin wallet is equally vulnerable. The most discussed risk involves wallets whose public keys have already been exposed on-chain. Recent developments have given rise to the concept of “harvest now, decrypt later,” where bad actors are compiling public keys and waiting for future quantum computers to catch up.

Galaxy Digital is expected to announce negative $0.93 earnings per share for Q1
Galaxy Digital will post Q1 results before opening hours on Tuesday. The investment company will give a lagging indicator of the overall crypto market performance. Galaxy Digital (Nasdaq: GLXY) is expected to post weakened results in Q1, with negative earnings per share. Q1 was a challenging period for crypto markets, with multiple indicators softening further. The quarter was exacerbated by several high-profile hacks and an overall fearful sentiment. Reminder that Galaxy will release Q1 2026 financial results before market open on Tuesday, April 28. CEO and Founder @novogratz , along with members of management, will host a conference call to provide an update on activities and results. pic.twitter.com/8EBjBhYwsi — Galaxy (@galaxyhq) April 27, 2026 Mike Novogratz’s fund has been active during previous boom cycles and has supported the growth of Solana. Now, the fund will face a reckoning with the weakened market. Ahead of the news, GLXY shares traded at $24.90, with a minimal net gain for the year to date. The stock is still up by over 62% for the past 12 months. Galaxy Digital faces expectations of weaker profits The upcoming report may reveal earnings per share of negative $0.93, indicating Galaxy Digital has struggled to remain profitable. The weakening crypto market led to nine downward revisions of the Q1 result for the past three months. Galaxy Digital adds to the overall negative sentiment of the crypto market. Despite this, GLXY shares are still considered undervalued. At the same time, GLXY stock comes with a mostly positive rating and buy recommendations. Firm Rating Price Target Date of Last Action Chardan Buy (Initiated) $35.00 April 27, 2026 Canaccord Genuity Buy $50.00 April 24, 2026 Rosenblatt Buy $39.00 April 23, 2026 Piper Sandler Overweight $36.00 April 21, 2026 BTIG Buy $50.00 April 14, 2026 Goldman Sachs Neutral $21.00 April 8, 2026 The results of Galaxy Digital may change the general sentiment and outlook for both crypto investors and mainstream stock buyers. The Q1 results will also show how successfully Galaxy Digital managed to pivot from its less successful crypto projects. GLXY shows slower trading of its tokenized version As Cryptopolitan reported , Galaxy Digital was among the first Nasdaq-listed companies to tokenize its native GLXY shares. About six months after the listing, GLXY shares show limited on-chain activity. In April, the company retired over 30K shares from its on-chain offerings. The biggest problem is the lack of adoption and trading, as only 81 holders hold a Solana version of the Galaxy common stock. The company has only tokenized 0.0075% of its shares on Solana, more as a proof of concept than a viable trading venue. The shares are also not accessible to crypto natives to trade, mint, or redeem. Ahead of the report, Galaxy Digital holds over $609M in crypto assets, with 4.56K BTC and 42,000 ETH. The fund invested in multiple tokens from previous bull markets, including Terra (LUNA). As of April 2026, the Galaxy Digital assets are mostly in the red, as the portfolio contains multiple tokens with no viable projects. Galaxy Digital has shifted from crypto to an AI play, currently building its 1.6 gW Helios campus for AI computation. The campus inherits the Galaxy Digital mining facilities in Texas and has the advantage of established energy infrastructure and contracts. The company has secured $1.4B in financing for its AI pivot, expected to complete the first stage of the Helios project.

Crypto expert Michaël van de Poppe predicts Bitcoin to hit this price in May
With Bitcoin ( BTC ) having recorded four consecutive bullish weeks, crypto expert Michaël van de Poppe expects the flagship coin to continue its uptrend in May 2026. Poppe made a bold BTC price prediction on April 27, based solely on technical analysis. He stated that the flagship coin could rally to a liquidity range of $85,000 to $88,000 in May, before experiencing either a correction or a consolidation. BTC/USDT 6-hour chart. Source: TradingView Poppe highlighted that Bitcoin price has consistently held above the resistance range between $71,438 and $73,408, which acted as a strong resistance zone in March. If BTC price is to hit this set resistance area, the analyst argues that buyers must turn the sell wall around $80,646 into support. The bullish target for May could be invalidated if BTC price reverses from its current resistance level around $79,127. Furthermore, the Relative Strength Index (RSI) has been forming a bearish divergence, amid a potential double top in the past week. Key factors that may influence Bitcoin price in May Bitcoin’s price in May could depend heavily on leverage and the spot market’s performance, as Finbold recently reported . With the April BTC price pump fueled by leveraged traders, if spot market buyers outpace net sellers, a further rebound could be possible next month. However, if spot demand, especially from spot BTC exchange-traded funds (ETFs), fades in May, a correction could be imminent since a leveraged-fueled bull rally is fragile. Meanwhile, Bitcoin’s price in May could be influenced by this week’s monetary policy decisions from the United States Federal Reserve, the Bank of Japan (BoJ), the Bank of Canada (BoC), the Bank of England (BoE), and the European Central Bank (ECB), as Finbold noted . Meanwhile, BTC’s volatility in May could be affected by the anticipated markup vote on the Clarity Act, a proposed U.S. regulatory framework to legalize crypto assets, as Finbold pointed out .

Is Bitcoin Becoming A Strategic Military Asset? US Admiral Hints At Deeper Role
Is Bitcoin quietly evolving beyond finance into a tool of national defense? That question is gaining traction after comments from Samuel Paparo, the commander of the United States Indo-Pacific Command, reported that BTC may have significance beyond markets, hinting at a role in cyber defense, power projection, and strategic competition. Paparo pulled back the curtain on a quiet but potentially significant shift in how the technology is being evaluated at the highest levels of defense. Could Bitcoin Support The Future Of Military Readiness? In a recent X post, an analyst known as TFTC updated that the head of the United States Indo-Pacific Command revealed that the US military is actively running a Bitcoin node and testing the protocol’s cryptographic architecture for operational security. Related Reading: Why Bitcoin Still Acts Like A Risk Asset Despite Safe-Haven Claims Furthermore, Paparo reportedly framed BTC as a tool for securing and protecting networks, and suggested its relevance to power projection in the context of strategic competition with China. Not mining, not speculating, but running infrastructure. The same network once mocked as a haven for criminals is now considered critical to national security by the Department of Defense. Meanwhile, the US is estimated to hold roughly 328,000 BTC, while China is believed to control around 194,000 BTC. Whether BTC was intentional or incidental, the military is treating it as an asset in a geopolitical arms race. A Message That Shifted Bitcoin Narrative Away From Mystery It has been 15 years since Satoshi Nakamoto handed Bitcoin to the world. Alex Thorn, the head of firmwide research, has stated that Nakamoto sent what is widely believed to be his last confirmed communication. Related Reading: Bitcoin Sees Renewed Demand From US Institutional Players — What’s Changing? On April 26, 2011, Satoshi wrote to Bitcoin developer Gavin Andresen, urging him to shift the narrative away from the shadowy figure and toward emphasizing BTC as an open-source project and community contribution. In the days leading up to that message, Satoshi had already begun stepping back. In a message to developer Mike Hearn on April 20 and 23, Satoshi said he had moved on to other things, reassuring him that BTC was in good hands with Gavin and everyone. His last public post was earlier on December 12, 2010, in his 575th post on the Bitcointalk forum. The focus was on warning about a potential DoS attack, and signing off with the fact that there was still more work to do. Fifteen years later, the coins remain untouchable. Satoshi holds roughly 1.097 million BTC, currently worth an estimated $85 billion, still sitting untouched. In Alex’s view, when Satoshi said BTC was in good hands, he wasn’t only speaking to early developers; he was speaking to all of us, and we must carry that legacy forward.
