Can Quantum Computing Really Kill Bitcoin? $85K Bounty Says It’s Time to Find Out

Bitcoin BTC’s $1.7 trillion network runs on elliptic curve cryptography (ECC), a security standard once thought to be unbreakable—until quantum computing entered the chat. Now, Project 11, a quantum research firm founded in 2024, has launched a bold challenge: crack a simplified version of Bitcoin’s encryption using a quantum computer, and win 1 BTC (currently ~$85,000).

Their goal? Understand how close quantum computing is to becoming a real threat. The contest—called the QDay Prize—is open until April 5, 2026, and allows teams to attempt breaking ECC keys from 1 to 25 bits. BTC uses 256-bit ECC, so the challenge is symbolic, but meaningful.

We just launched the Q-Day Prize.

1 BTC to the first team to break a toy version of Bitcoin’s cryptography using a quantum computer.

Deadline: April 5, 2026
Mission: Protect 6M BTC (over $500B)

“We’re not trying to break Bitcoin,” said Project 11’s Alex Pruden. “But if quantum computing can break even a small key, we need to prepare now.”

Traditional computers would need centuries to crack Bitcoin’s encryption. A quantum computer, however, could theoretically do it in minutes using Shor’s algorithm, a mathematical method that turns ECC’s strength—computational asymmetry—into a vulnerability.

That could expose users’ private keys, forge signatures, and allow attackers to drain wallets. It’s not sci-fi anymore. As quantum technology accelerates, even blockchain titans are hedging their bets.

• Solana launched its Winternitz Vault earlier this year—using hash-based, quantum-resistant signatures.
• Ethereum’s Vitalik Buterin has proposed a quantum-resistant hard fork for ETH.

Bitcoin? So far, no active hard fork plans, but initiatives like Project 11’s challenge are pushing the community toward preparedness.

Project 11’s competition is more than a coding contest. It’s a stress test for the future of crypto security. Even a 5-bit key breach would signal that quantum computing is advancing faster than anticipated.

Key Takeaways:

• Project 11’s 1 BTC bounty is live until April 2026.
• The challenge uses scaled-down ECC keys to assess risk.
• A real-world quantum breach could compromise billions in crypto.
• Ethereum and Solana are already investing in quantum defenses.

“We don’t know how far off ‘Q-Day’ really is,” said Pruden. “But when it arrives, we need to be ready.”

Bitcoin (BTC) is tightly consolidating within a symmetrical triangle on the 1-hour chart, suggesting an imminent breakout. Price is hovering around $84,588, testing the triangle’s apex while holding just above the 50 EMA at $84,587—a key short-term support level.

This compression pattern, formed from the A-B-C-D wave sequence, reflects indecision but typically resolves with a sharp directional move. A confirmed close above $85,508 could unleash a rally toward $86,385, while a breakdown below $84,454 might expose $83,774 or $83,111.

The MACD shows a fading bullish momentum, with the histogram weakening and the lines nearing a bearish crossover—adding caution to the near-term outlook.

Trade Setup:

• Entry: Buy on breakout above $85,508 with strong volume
• Target: $86,385
• Stop Loss: Below $84,450

Wait for confirmation—breakouts without volume often fail. Patience is key in tight-range setups like this.

As Bitcoin edges closer to the $85,000 mark and macro uncertainty intensifies, BTC Bull Token ($BTCBULL) continues to gain traction with retail and crypto-savvy investors. This Ethereum-based meme coin stands out by offering real Bitcoin airdrops every time BTC hits key price milestones—aligning directly with Bitcoin’s long-term upside.

Beyond the airdrop rewards, BTC Bull’s staking program remains a major draw. Investors can earn up to 86% APY in passive income, while also contributing to the token’s network strength. The ability to unstake anytime makes it flexible for new and seasoned holders alike.

Staking Snapshot:

• Annual Yield: 86% APY
• Total Staked: 1,222,531,969 BTCBULL
• Unstake Anytime: Yes

With over 1.22 billion tokens already staked, momentum continues to build ahead of the next price milestone.

The presale is now approaching full subscription, with $4,769,780.40 raised out of the $5,466,194 target. The current token price remains at $0.002465, but with limited supply left and rising demand, a price hike could be imminent.

Latest Presale Stats:

• Token Price: $0.00247
• Raised So Far: $4.77M of $5.47M

This window may be one of the last chances to secure BTCBULL before the next pricing tier kicks in. With its high-yield staking, real BTC rewards, and growing ecosystem engagement, BTC Bull is emerging as a top contender in the meme coin space—backed by actual Bitcoin utility.

With limited time remaining and demand accelerating, this is a key window to secure BTCBULL at presale rates before the next price jump.
