š§ Bitcoin vs. Quantum Computers: Real Threat or Just Noise?
For years, quantum threats felt like sci-fi. Now? Not so much.
Google + IBM say breaking encryption might be possible sooner than we think ā maybe even before 2030. š³
š¹ Quantum tech is catching up.
š¹ Experts say BTCās cryptography could be cracked.
š¹ Some suggest migrating coins to quantum-safe wallets ASAP.
š¹ Others, like Adam Back, say itās still 20+ years away.
But what if theyāre wrong?
What if 8000 quantum chips really can break SHA-256?
Is Bitcoin ready for a cryptographic upgrade... or are we still too early to panic?

When Bitcoin is under Threat: Are Quantum Computers Really that Close to Breaking Cryptography?
Listen, I want to share a topic that came up in the news, and it's really interesting. It's about quantum computers and Bitcoin. It sounds like science fiction, but it seems that the time of fiction is coming to an end.
So, several major figures in the world of technology and cryptocurrencies have started sounding the alarm again: what if a quantum computer can hack Bitcoin? Like, it's really possible to open wallets, change transactions, and generally undermine everything that the blockchain stands for.
Here are the opinions I've gathered:
IBM and 2029
IBM plans to release a new generation quantum computer, Quantum Starling, by 2029. It will be a fault-tolerant (that is, stable, non-malfunctioning) quantum computer, which has not been done before. It is believed that such machines will be able to cope with tasks like breaking cryptography.
Google: Is the threat closer than it seems?
In May 2025, Google researcher Craig Gidney rolled out calculations according to which 20 times fewer quantum resources are needed to crack RSA encryption than previously thought. Yes, Bitcoin uses elliptic curves (ECC) instead of RSA, but they are also vulnerable to the Shore algorithm ā and Gidney confirmed this.
He estimated that with less than a million qubits, powerful encryption could be cracked in just a week. It doesn't sound like 2100 science fiction anymore.
Who says "not so scary"?
Adam Back, one of the veterans of the bitcoin scene and the head of Blockstream, says: don't panic. He believes that there will be no truly dangerous quantum systems for another 20 years, but he still advises transferring coins to quantum-stable addresses in advance, especially if these are the same ancient coins, such as from Satoshi's cache.
The most disturbing voice
David Carvalho of Naoris Protocol does not stand on ceremony: in his opinion, hacking can happen within 5 years if Bitcoin does not urgently switch to new cryptographic standards. He even refers to a report by BlackRock ā yes, the very investment giant - which explicitly states that the quantum threat is taken into account when applying for an ETF.
He also mentions that up to 30% of all bitcoins are stored at vulnerable addresses, and one successful breach can lead to a loss of trust in the entire network.
And what now?
Well, the cherry on the cake is investor Chamat Palihapitiya. At the end of 2024, he suggested that SHA-256ā the Bitcoin hashing algorithm, could be broken in 2-5 years. According to him, 8000 quantum chips like those that Google has already made are enough, and that's it. Although for now, scaling such a thing is a separate pain.
So, on the one hand, supercomputers are still not ready, but on the other, everything is moving much faster than expected, and the big players understand this.
Do you think Bitcoin should switch to a new cryptography right now ā or are these threats still from the category of "just in case"?

Is Microsoft Accelerating the Threat of Quantum Attacks for Bitcoin?
On February 19, Microsoft unveiled a new quantum chip, Majorana 1, which could bring the moment when quantum computers will be able to hack cryptocurrency closer. According to River, by 2027ā2029, a quantum machine with a million qubits will be able to attack Bitcoin addresses if it operates for several days or weeks.
River CEO Alexander Leishman warns: āEven if the threat is in the future, we need to prepare now.ā However, critics consider the fears exaggerated. Firstly, quantum technologies can strengthen Bitcoin itself, and secondly, banks with $188 trillion in assets will be the first targets of hackers, and not the crypto market with $3.2 trillion.
Cryptographer Adam Back is sure that the real threat is decades away, and solutions already being developed, such as BIP-360, can make Bitcoin quantum-resistant through a soft fork.
Conclusion? Time will tell. But if the quantum apocalypse comes, are your assets ready? Find out how to protect your Bitcoin today! šš„ #CryptoFuture #Bitcoinā #quantumcomputing

Pt.2: The Quantum Threat to Crypto Assets
Quantum computers pose a significant challenge to the security of cryptocurrencies and blockchain-based assets. Current cryptographic systems rely on mathematical problems that are extremely hard for classical computers to solve, like factoring large prime numbers. However, quantum algorithms such as Shorās algorithm can solve these problems exponentially faster.
Here are the four main risks posed by quantum computing to crypto assets:
Breaking Private Keys
Quantum computers can break the cryptographic schemes protecting private keys, making it possible to steal funds from wallets. Itās estimated that around 4,000 logical qubits would be needed to break widely used public-key cryptography, such as RSA and ECC (Elliptic Curve Cryptography).
Dominating Mining
Quantum computers could outperform classical miners, monopolizing block creation and disrupting the networkās fair distribution of rewards.Smart Contract Vulnerabilities
Quantum attacks can target smart contracts and decentralized applications, potentially changing their behavior or bypassing security measures.
Loss of Trust
If quantum attacks become feasible, trust in blockchain networks could erode, leading to a collapse in confidence and the value of digital assets.
Currently, the IBM Condor chip ā with 1,121 qubits ā represents a major milestone. Googleās research suggests that millions of physical qubits would be needed for large-scale quantum error correction, so weāre not yet at the point of quantum supremacy in breaking crypto, but progress is accelerating.
