Bitcoin has had a hesitant week, slipping lower before finding its feet at a level of support that has held strong for months now. Easing bond yields and cheaper oil gave markets something to cheer about, but nobody wanted to get carried away ahead of Tuesday’s inflation print. Today’s forward guidance looks at what those numbers might mean for crypto’s next move.

Away from the macro, Crypto Twitter has found something rather more existential to fret about. Ethereum Foundation researcher Justin Drake has urged holders to prepare for what he calls “bunker mode”, warning that AI’s growing knack for mathematical breakthroughs could leave the cryptography protecting our wallets vulnerable far sooner than expected. Not everyone is convinced, mind - other experts have been quick to dismiss the warning as textbook FUD. Full story below.

🚧 Pipe Dreams 🚧

The AI boom was supposed to be unstoppable. Eye-watering sums are being poured into data centres across America, and Stargate - unveiled with great fanfare at the White House - was meant to be the project that proved it could all be done at breakneck speed.

But for all the cutting-edge chips and clever models, its flagship site is being held up by something altogether more mundane - and the whole thing has been built on a mountain of borrowed money. So, in today’s video, we break down what Stargate was meant to be, what’s actually standing in its way and who ends up footing the bill if it runs late. We also follow the debt all the way up to a certain tech billionaire with a borrowing habit of his own.

📈 Crypto Market Forecast 📈

The week ended with BTC just above $82k, down roughly 4% from the start of the period after a dip to $80,400 that saw a lot of longs nuked. It remains above the key support zone that has held through every test since August - a Glassnode analysis this week identified the largest cluster of buy orders sitting near $81k, which is where the dip found its floor. The rally from $57k has not been broken, but the ceiling at $86-87k that capped the September high has also not been overcome.

The week's price action was shaped by two contradictory forces. The first was falling yields and cheaper oil - both moderately bullish for risk assets. The 10-year Treasury yield pulled back slightly from its 5.24% peak, and Brent crude retreated from recent highs as fears of an immediate Iran escalation faded. The second was the anticipation of Tuesday's September CPI print, which has kept buyers cautious.

When it comes to the CPI release, headline inflation is expected to come in at 3.6-3.7% YoY, driven largely by record petrol prices in September. Core CPI - which excludes food and energy and is the number the Fed actually cares about - is expected near 2.4% YoY, which would be the lowest reading of the current tightening cycle. The divergence between headline and core is the key dynamic to watch here. A hot headline driven by energy would normally cause knee-jerk selling; but if the Fed and markets look through it to a softening core, the reading would support the idea of a pause in rate hikes. October hike probability has now fallen to roughly 1-in-4, down from 47% at the start of last week.

So, a benign core CPI print on Tuesday would remove the last meaningful near-term argument for a hike. It would put a November rate cut back on the table, weaken the dollar, and give BTC the catalyst it needs to break through the $86-87k ceiling that’s now acted as resistance three times since August. The rebound from the mid-September low of $75k through to the $87k high was the move that confirmed the recovery. What comes next depends on whether CPI provides the confirmation that the tightening cycle is actually over.

In sum then, BTC is consolidating above support with the 14th October CPI as the defining near-term event. A soft core print would trigger the move toward $87-89k and likely give some ammo to those calling for $100k by the end of the year. A hot headline print driven by energy would create short-term noise but should be bought into if core remains well-behaved. The worst scenario would be core coming in much higher - that would revive talk of a rate hike at the FOMC meeting this month and push BTC back toward $80-81k support. Let us pray.

🔏 Bunker Mode 🔏

Back in April, we wrote about how Anthropic’s latest model class, Claude Mythos, had managed to find software bugs that had survived 27 years of human audits. At the time, this news triggered widespread panic amongst the wider tech community, with many wondering whether their software systems were still secure.

Within crypto, the main concern was that someone would eventually point a model like that at smart contract code. Separately, a paper published back then by Google Quantum AI estimated that breaking elliptic-curve cryptography needed roughly twenty times fewer physical qubits than previous estimates had suggested.

In other words, the attack vector for the crypto industry from AI and compute advancement did not just include smart contract exploits but also the very wallet signatures used to move and secure assets on the blockchain. This development saw some experts predict a 10% chance of quantum computers being able to crack a Bitcoin or Ethereum private key from an exposed public key by 2032.

That said, this panic was ultimately quelled by independent researchers stating that the capability jumps, although real, did not pose an imminent threat. Big AI’s promise to restrict the public release of such advanced models also helped soothe concerns.

For crypto specifically, many of the big infra leaders began planning for quantum migration; a transition to post-quantum cryptography. Ethereum, in particular, has planned a multi-fork migration expected to make the network quantum-ready by 2029. In other words, the industry seemed to have come with a plan to combat this inevitable threat despite its initial panic.

This makes the latest wave of cybersecurity FUD on CT all the more concerning.

On 7th October, Ethereum Foundation researcher Justin Drake made an X post calling on the industry to calmly begin planning for what he called "bunker mode." In simple words, he wants crypto holders, especially the largest ones, to move their assets to fresh addresses that have never sent a transaction.

He stated that he now believes existing wallet signatures might become vulnerable sooner than expected, with the worst-case scenario putting this risk at “months, not years.” For context, Drake’s latest warning follows OpenAI publishing a repository of mathematics written by an unreleased internal model.

This repository contained 722 manuscripts with results covering a wide range of mathematics and theoretical computer science. Some of these manuscripts challenged long-standing conjectures or improved existing algorithms. Put simply, AI is making mathematical research more capable. In other words, Drake isn’t worried about quantum computing but rather the growing ability of AI models to discover mathematical results that human researchers have long struggled to find.

Although the repository admits that some results without formal proofs could contain issues, Drake’s larger point is that previously long-standing mathematical beliefs are being disproved by advanced AI models. In fact, just a day before OpenAI’s repository was released, two well-known complexity theorists posted a paper overturning a decades-old conjecture about a problem called 3SUM, with the key idea reportedly supplied by an Anthropic model.

Although none of the manuscripts in OpenAI’s repository relate to cryptography, Drake points to the hardness of ECDSA (Elliptic Curve Digital Signature Algorithm) as yet another mathematical belief held without proof.

In case you didn’t know, this cryptography is used for the signatures protecting ordinary Bitcoin and Ethereum wallets. To understand the cause for concern, it helps to understand how a crypto wallet works at a technical level.

A crypto wallet contains a private key (secret number) that proves ownership of assets on the blockchain. Anyone with access to a wallet’s private key can move the assets held by the wallet. To publicly verify that the signatures are valid, blockchains use a public key derived from the underlying private key.

The security of the system depends on the difficulty of working backwards. While generating a public key from a private key is relatively straightforward, the general understanding is that recovering the private key from the public key is computationally infeasible with currently known classical algorithms and practical computing resources. In other words, the current belief is that this cryptography is mathematically hard enough that only quantum computers are capable of breaking through it.

Drake’s concern though is that this might prove to be false as AI gets better at mathematical breakthroughs.

That said, this public key is generally not directly exposed through an ordinary Ethereum transaction history until the wallet signs a transaction. This means that wallet addresses that have only received funds are safe from having their public keys exposed this way. This is why Drake recommends users move their funds to a new wallet address that has never signed transactions.

However, other experts have already started pushing back against Drake’s assertion. Notably, Yehuda Lindell, Coinbase's head of cryptography, wrote that there is "no evidence whatsoever pointing to a break of decades old hardness assumptions like elliptic curve cryptography." He called the warning "the very definition of FUD" on the grounds that it is impossible to disprove and equally impossible to support.

Despite this pushback, a few things make Drake’s warning worth listening to. Notably, there is one documented case of an AI system damaging real cryptography this year. In July, Anthropic reported that its Claude Mythos Preview model had found a faster key-recovery attack on HAWK, a signature scheme under consideration as a US post-quantum standard. The work took about 60 hours of mostly autonomous effort and roughly $100,000 of compute, and it cut the cost of attacking the smallest version from 2^64 operations to 2^38. HAWK's authors have since withdrawn it from the standardisation process.

While Anthropic was careful to say the attack is specific to HAWK, it’s worth noting that HAWK is built on lattices, the family of mathematics most of the world is planning to migrate to once elliptic curves are retired. In other words, there’s a real cause for concern.

Ethereum founder Vitalik Buterin has also shared his own thoughts on the matter. While he acknowledges the risk highlighted by Drake, Buterin has discouraged users from rushing to move their funds to new wallets. While he says keeping funds in unused addresses is a good idea, he warns that the move itself can be problematic if not done right. He stated, "I personally have lost more money in botched migrations than I have lost in all hacks combined."

If you’re worried about all of this, there’s a simple check to see if your own wallet is exposed – that’s to see if there are any outgoing transactions across the different networks (Ethereum, Base, BNB, etc) on your EVM wallet address. While receiving funds keeps the key hidden, a single send publishes your key for good, even if it was a test transfer years ago.

If the checks come back exposed, the answer for now is to sit tight. If you plan to hold long-term in cold storage, then generate a new receive-only address and send your funds to that wallet. Though, as Vitalik has advised, be careful. We are likely to see a new wave of scams promoting fraudulent migration services as they capitalize on the FUD. For those active in DeFi, you are better off waiting for smart-contract wallets that can swap their signature schemes. Until then, stay safe folks..
