Hoskinson Predicts $250K Bitcoin as Cardano Prepares for Quantum Threats

Cardano founder Charles Hoskinson has warned that quantum computing could create serious challenges for Bitcoin while outlining a multi-year plan to strengthen Cardano's cryptographic security. In an interview with Anna Tutova, founder of AI Crypto Minds, he also discussed Midnight's institutional ambitions, autonomous AI agents, and his prediction that Bitcoin could reach $250,000 within the next 24 months.

The conversation connected three developments that Hoskinson believes could reshape blockchain adoption: post-quantum protection, privacy-preserving financial infrastructure, and an emerging economy powered by autonomous AI agents.

Cardano's Quantum Security Plan Could Take Three to Five Years

Quantum computing was among the most technically detailed subjects discussed during the interview.

Hoskinson argued that blockchain networks already have access to promising post-quantum cryptographic algorithms. The challenge is implementing them without significantly increasing transaction costs or reducing network performance.

The National Institute of Standards and Technology has published three major post-quantum cryptography standards, FIPS 203, 204, and 205, covering key establishment and digital signature technologies designed to withstand attacks from future quantum computers.

However, replacing existing cryptography is not a simple software upgrade.

Hoskinson warned that some post-quantum approaches could increase transaction sizes and computational requirements by factors of ten to one hundred, depending on the algorithms and implementations involved.

For Cardano, the transition would also require adaptations to its proof-of-stake infrastructure, including cryptographic mechanisms used in consensus and validator selection.

He revealed that Cardano has a dedicated quantum security research group and maintains contact with specialists involved in developing cryptographic standards.

Hoskinson also highlighted Nightstream, an initiative included in Midnight's technical roadmap that focuses on post-quantum zero-knowledge proofs. Its development targets include reducing proof generation time and proof size, making quantum-resistant privacy technologies more practical for blockchain applications.

According to Hoskinson, Cardano could introduce the required cryptographic changes over the next three to five years.

He emphasized that the transition could be accelerated if technological developments made quantum threats more immediate. However, the interview did not establish a specific implementation schedule or hard fork date.

The timing remains uncertain.

Hoskinson referenced DARPA's Quantum Benchmarking Initiative, a program examining the feasibility of developing industrially useful quantum computers. While he discussed the possibility of such capabilities emerging around 2031, DARPA's published assessment focuses on whether useful systems could be achieved by 2033.

His strongest concerns were directed toward Bitcoin.

Hoskinson argued that older Bitcoin holdings, including coins associated with Satoshi Nakamoto, could become vulnerable if sufficiently powerful quantum computers are eventually able to break the cryptography protecting exposed public keys.

The issue extends beyond introducing new signature algorithms.

Bitcoin would also need a migration strategy for existing holdings, including assets controlled by inactive users or private keys that may no longer be accessible.

Hoskinson believes Cardano's on-chain governance provides a more structured process for coordinating major protocol changes.

Bitcoin can also adopt upgrades through network consensus, but it does not have Cardano's formal on-chain governance voting framework.

Neither approach automatically solves the problem of migrating assets whose owners cannot authorize new transactions.

For Cardano, Hoskinson's proposed three-to-five-year transition remains a development objective rather than confirmation that the network is already quantum-resistant.

Midnight Targets Private DeFi Across Major Blockchain Networks

Hoskinson also addressed what he considers one of cryptocurrency's biggest unresolved problems: the gap between technological adoption and everyday usability.

Despite the industry's substantial growth, he argued that blockchain applications remain too complicated and risky for mainstream consumers.

Managing wallet addresses, recovery phrases, network compatibility, and transaction security still requires knowledge that ordinary financial applications rarely demand.

His proposed solution combines privacy, simplified interfaces, interoperability, and stronger consumer protection.

Hoskinson described Midnight as a VPN for decentralized finance.

The comparison reflects Midnight's goal of allowing users to interact with supported financial applications without publicly exposing all the information normally associated with transparent blockchain transactions.

Instead of requiring users to abandon their existing networks, Midnight aims to introduce privacy-preserving execution and transaction coordination across multiple ecosystems.

Hoskinson discussed integrations involving Cardano, Solana, Bitcoin, and Ethereum.

Solana wallet interaction with Midnight has already been demonstrated in a testnet environment, while broader production integration remains part of ongoing development.

Hoskinson expressed confidence that Midnight could eventually facilitate DeFi activity across networks representing approximately 95% of the market's trading activity within six to twelve months.

That figure represents his ambition for interoperability coverage, not a verified share of transactions already supported by Midnight.

Institutional finance is another major component of the strategy.

Hoskinson explained that regulated financial institutions require controls that ordinary public blockchain transfers do not automatically provide.

These include identity verification, conditional settlement, compliance checks, and restrictions on transfers involving prohibited counterparties.

Privacy-preserving technologies could allow such requirements to be verified without exposing every customer's financial information publicly.

He identified Monument Bank as an important example of this approach.

The UK-regulated bank announced a partnership with Midnight Foundation in March 2026, initially targeting £250 million in tokenized, interest-bearing customer deposits.

During the interview, Hoskinson described the possibility of expanding that activity to several billion pounds over time.

The larger figure remains a longer-term ambition, not an amount already transferred onto Midnight.

The architecture is intended to connect regulated financial products with blockchain infrastructure while preserving institutional compliance requirements and customer confidentiality.

Hoskinson believes similar systems could eventually support a broader range of banking services, insurance products, and institutional DeFi applications.

Their availability would depend on further technical development, regulatory approval where required, and commercial deployment.

Midnight City Plans Autonomous AI Trading as Hoskinson Predicts $250K Bitcoin

The interview also provided details about Midnight City, Hoskinson's experimental environment for autonomous AI agents.

Rather than functioning as conventional chatbots, agents within Midnight City are designed to operate inside a persistent digital world, developing identities, relationships, occupations, and economic activities.

Hoskinson described a future in which these agents communicate with one another, discover services, negotiate access to information, and perform transactions on behalf of their users.

One of the clearest development targets concerns cryptocurrency trading.

According to Hoskinson, autonomous trading functionality is expected to become available in Midnight City within three months of the interview.

The proposed system would allow users to allocate funds to an AI agent's wallet and instruct it to trade cryptocurrencies such as Bitcoin, Ether, or Solana.

The agent could then execute strategies using the financial resources and permissions assigned to it.

An additional component would introduce a marketplace for proprietary trading strategies.

Developers could create strategies and license them to other agents, potentially receiving royalties when those strategies are used.

Trusted execution environments could help protect the underlying trading logic, allowing agents to execute proprietary strategies without revealing their internal implementation.

That model would create a marketplace for AI skills and specialized financial knowledge.

However, the interview did not confirm that unrestricted live trading is already available or provide verified performance results for the proposed strategies.

Autonomous trading would also introduce operational risks involving wallet permissions, trading losses, and the ability of agents to execute instructions reliably.

Hoskinson connected this vision to technologies such as x402 and the Open Wallet Standard, which could help AI agents access financial services and make digital payments.

He argued that autonomous agents will increasingly need economic identities, payment mechanisms, and ways to compensate other agents for providing data, computational resources, or specialized services.

Blockchain networks and stablecoins could provide part of that infrastructure.

This expectation also shaped his cryptocurrency market outlook.

Hoskinson predicted that Bitcoin could reach $250,000 within the next 24 months.

Although the interviewer also asked about Cardano and NIGHT prices, he did not provide specific price targets for ADA or NIGHT.

Instead, he linked their longer-term prospects to the development of applications capable of generating real economic activity.

He suggested that AI-driven payments, decentralized computing, and autonomous financial transactions could eventually increase activity on some blockchain networks by tenfold or even one hundredfold.

Those figures represent his expectations rather than forecasts supported by a published economic model.

Hoskinson's $250,000 Bitcoin prediction therefore rests alongside a different, more immediate development target. Within three months of the interview, Midnight City is expected to introduce autonomous trading, offering a practical test of whether AI agents can manage allocated funds, execute private strategies, and compensate developers for the financial capabilities they provide.
