Quantum Computing: The Overhyped Bitcoin Boogeyman That Just Won’t Show Up

by

Once again, the specter of quantum computing has risen like a bad penny, raising concerns that it could one day shatter the fragile glass of Bitcoin‘s cryptography. But fear not! A freshly minted report from CoinShares insists that any quantum risk is still as distant as the next lunar landing, with only a scant portion of Bitcoin’s supply teetering on the edge of vulnerability.

This report, as grand as a tale spun by an old storyteller, frames quantum computing as a long-term engineering conundrum, suggesting that Bitcoin has plenty of time to don its metaphorical armor well before quantum machines can muster enough power to pose a real threat. So, grab your popcorn; this show is just getting started.

The Quantum Threat Assessment For Bitcoin

In a riveting read titled “Quantum Vulnerability in Bitcoin: A Manageable Risk,” CoinShares’ Bitcoin Research Lead, Christopher Bendiksen, paints a picture where Bitcoin relies on elliptic-curve cryptography-the digital equivalent of a moat around a castle-to secure transactions.

Now, in theory, if someone were to wield a quantum computer powerful enough, they could whip out Shor’s algorithm like a magician pulling a rabbit from a hat, extracting private keys from public keys and unleashing a spending spree without permission. Quite the heist, huh?

However, our hero Bendiksen notes that pulling off such a stunt would require quantum machines with millions of stable, error-corrected qubits-something akin to waiting for pigs to fly. We’re talking about technology that’s light-years ahead of our current capabilities.

“Breaking secp256k1 within a practical amount of time (<1 year) needs 10-100,000 times the current number of logical qubits; relevant quantum tech at least 10 years off. Long-term attacks can take place over years-could become feasible within a decade; short-term (mempool attacks) need <10-min computations-infeasible in anything but the very long term (decades),” the report read.

As it turns out, Bendiksen also ventured into the realm of Bitcoin’s actual exposure. Only about 1.6 million BTC, or roughly 8% of the total supply, lingers in legacy Pay-to-Public-Key (P2PK) addresses, where public keys have already done the unthinkable and shown themselves. But hold your horses; the genuine risk is much smaller than a flea on a dog.

Of that amount, only around 10,200 BTC might be worth targeting in a way that would cause a stir. Yes, you heard that right-less than 0.1% of Bitcoin’s total treasure trove. So, what’s the fuss all about?

“The remaining ~1.6 million all sit in 32,607 individual, ~50 btc UTXOs, that would take millennia to unlock even in the most outlandishly optimistic scenarios of technological progression in quantum computing,” Bendiksen stated.

The rest of those elusive coins are scattered across tens of thousands of addresses like confetti at a parade. This distribution makes large-scale exploitation about as practical as herding cats, even for the fanciest quantum systems, according to the analysis.

This limited exposure is thanks to modern address types. Pay-to-Public-Key-Hash (P2PKH) and Pay-to-Script-Hash (P2SH) keep the public keys under wraps until coins are spent, sharply reducing the attack surface. It’s almost like a well-guarded secret.

While there’s chatter about post-quantum cryptographic proposals, Bendiksen warns against hasty changes that could introduce new risks, weaken decentralization, or rely on schemes that haven’t yet been tried and tested in the wild.

“For the perceivable future, market implications appear limited,” Bendiksen added, as if imparting wisdom from a sage of old. “The greater concern is preserving Bitcoin’s immutability and neutrality, which could be jeopardised by premature protocol changes.”

Meanwhile, this cheerful outlook falls in line with opinions from other industry figures who’ve echoed similar sentiments. Casa co-founder Jameson Lopp and Cardano founder Charles Hoskinson both seem to agree that quantum computing isn’t the villain lurking in the shadows, ready to pounce on Bitcoin’s cryptography.

Quantum Risk No Longer Ignored as Investors and Developers Prepare

Yet, not everyone in the marketplace is sipping from the same Kool-Aid. Some institutional investors are starting to factor quantum computing risks into their Bitcoin exposure, rather than tossing it aside like yesterday’s news.

BeInCrypto reported that strategist Christopher Wood decided to trim a 10% Bitcoin allocation from Jefferies’ model portfolio, shifting funds toward gold and mining equities. This came amid fears that future leaps in quantum computing could upend Bitcoin’s security faster than you can say “quantum entanglement.”

On the proactive front, several blockchain projects are already gearing up for a post-quantum world. Coinbase, Ethereum, and Optimism have all made public gestures to prepare for whatever quantum chaos may come.

Charles Edwards of Capriole Investments even suggested that Bitcoin’s price might need to dip further before the network catches wind of quantum security concerns. He presented market pressure as a potential spark for broader discussions-because nothing says “let’s chat” like a nosedive in prices.

“$50K not that far away now. I was serious when I said last year that price would need to go lower to incentivize proper attention to Bitcoin quantum security. This is the first promising progress we have seen to date,” he said.

Edwards wrapped up his thoughts with a warning that substantial work remains ahead, indicating Bitcoin’s quantum preparedness efforts would need to kick into high gear in 2026. After all, in the world of technology, the only constant is change-and perhaps a little bit of chaos.
