The foundational promise of cryptocurrency is decentralized, sovereign ownership. But this promise has run into a far more sobering reality, as a lot of funds held on centralized exchanges have been lost over the years. Users have learned the same lesson in different forms: Not your keys, not your coins.

Cointelegraph Research’s latest report, produced in collaboration with Trezor, the original hardware wallet, and titled “The Future of Self-Custody: Turning Ownership Into Security,” examines how this realization has reshaped investor behavior. Drawing on survey responses, post-mortem analyses of exchange failures, and a breakdown of modern wallet architectures, the report explains why self-custody should be a defining topic for crypto security in 2026.

Survey data shows a decisive erosion of trust in centralized exchanges. A majority of respondents now trust exchanges less than they did a year earlier, with the memory of the FTX collapse remaining a key psychological driver. Even regulatory frameworks such as MiCA, which improve custodial oversight, do not alter the underlying dynamic. Users increasingly recognize that custodial access can be restricted or withdrawn by decisions outside of their control. Migration into self-custody has therefore become a form of risk management.

Once assets move into self-custody, security no longer depends on institutional controls but on the user’s operational discipline. The survey shows that most users converge on a simple architecture, yet many still misunderstand that while hardware wallets meaningfully reduce the risk of remote compromise, they do not eliminate losses caused by the user.  

As a result, the report shifts the focus from device choice to behavior: how transactions are verified, how recovery material is stored, and how users model real-world threats.

The central conclusion is that turning ownership into security is not achieved through regulation, branding, or devices alone. It is a behavioral practice that depends on disciplined use of devices and an accurate understanding of what custody does and does not protect against.

[PRESS RELEASE – Tel Aviv, Israel, March 12th, 2026]

Playnance, a Web3 infrastructure company focused on blockchain-based digital entertainment platforms, is set to launch G Coin on March 18th, the utility token powering activity across its ecosystem of on-chain gaming, prediction markets, and interactive financial platforms.

Unlike many token launches that precede product adoption, G Coin enters the market as part of a live ecosystem already processing significant daily activity. According to Playnance’s public tracker, the token currently has more than 200,000 holders, with approximately 13 billion G Coin distributed during the presale phase and an estimated market capitalization of around $38 million ahead of its Token Generation Event.

G Coin functions as the unified economic layer of the Playnance ecosystem, facilitating gameplay activity, predictions, settlements, rewards, and other forms of participation across the network’s platforms. The token operates on PlayBlock, Playnance’s blockchain infrastructure, which enables fast, gasless interactions while maintaining non-custodial ownership and on-chain transparency.

The broader Playnance ecosystem operates at scale across a network of digital entertainment platforms. The infrastructure supports more than 300,000 registered accounts, integrates with over 30 game studios, and runs more than 10,000 on-chain games. Across the network, platforms process approximately 2 million on-chain transactions per day and support interaction with more than 2.5 million sports events annually. Together, these platforms form a high-volume on-chain environment where millions of daily interactions are powered by G Coin across gaming, sports events, and financial prediction markets.

“On March 18, G Coin will enter the market with real adoption already in place,” said Pini Peter, CEO of Playnance. “With more than 200,000 holders and millions of daily on-chain interactions, G Coin introduces a usage-driven token economy designed to grow alongside its expanding global community. There are many other surprises on the way to take the entertainment world to the next level, stay tuned”

Recent ecosystem developments have reflected continued activity growth ahead of the token launch. Earlier this year, Playnance reported that its “Be The Boss” program surpassed $2 million in real cash payouts to participants, while the broader ecosystem generated more than $5.3 million in total revenue.

G Coin operates within a fixed supply model capped at 77 billion tokens, with no future minting. Supply management is handled through a structured lock and release mechanism designed to moderate circulating supply. Tokens lost through gameplay are locked for 12 months before returning to circulation according to their original loss date, while unsold tokens at the Token Generation Event are subject to a 12-month cliff followed by a 24-month linear vesting schedule.

With the launch of G Coin, Playnance formalizes the economic layer supporting its digital entertainment infrastructure, connecting gameplay, sports events, prediction markets, and partner platforms within a single on-chain ecosystem.

Playnance focuses on reducing friction between user experience and blockchain infrastructure by abstracting complexity while maintaining full on-chain transparency and non-custodial architecture.

US investment manager Ark Invest claims that the lion’s share of the Bitcoin supply is already safe from the quantum computing breakthrough, leaving ample warning signals for builders to quantum-proof the rest of the supply.

Around 65.4% of the Bitcoin (BTC) supply is not vulnerable to the threat of a quantum computing breakthrough, but about 34.6% of the BTC supply remains at risk, according to a Wednesday white paper published by Ark Invest and Bitcoin-focused financial services company Unchained.

This includes around 5 million BTC, or 25% of the total supply, assumed migratable due to address re-use, and 1.7 million BTC, or 8.6% of the supply, assumed lost in P2PK (Pay-to- Public-Key) addresses, the earliest form of transaction script on the Bitcoin blockchain, which locked funds directly to public keys. Another 200,000 BTC (around 1%) is assumed to be migratable due to the address type P2TR (Pay-to-Taproot).

This supply would be vulnerable to quantum theft if quantum computers can break Bitcoin’s elliptic curve cryptography (ECC), which would require about 2,330 logical qubits and tens of millions to billions of quantum gates, the report argued.

“Even so, their practical feasibility would require quantum systems to reach performance levels that our research suggests will take much time to achieve.”

The paper’s estimates are far broader than those in a February CoinShares analysis, which said the realistically market-relevant portion of quantum-vulnerable Bitcoin was about 10,200 BTC, or roughly 0.05% of supply, even though legacy P2PK addresses account for a much larger theoretical exposure.

Separately, the first quantum computer facility with one million physical qubits (the equivalent of tens of billions of typical computers) is expected to be finished in 2027 by Chicago-based PsiQuantum, which raised $1 billion from BlackRock-linked funds.

Quantum breakthrough remains “long-term risk” for Bitcoin

Ark’s white paper argues that quantum risks will evolve over an extended period with “many intermediate warning signals” rather than an abrupt single point of failure.

Quantum breakthrough remains a “long-term risk,” rather than an imminent threat to the Bitcoin network, which gives the community time to “research and make plans for protecting the network” against the protracted development of quantum capabilities, the paper states.

Ark Invest foresees five stages for quantum computing advancements, but said that only the final stage of advancements will break ECC quicker than Bitcoin’s 10-minute block time.

Bitcoin held in quantum-vulnerable addresses should not be at risk until stage 3, when a quantum computer can break the 256-bit ECC key.

The white paper said that the first public key may be broken in the mid-2030s, citing a consensus target by companies including Google, IBM and Microsoft.

Bitcoin must implement quantum-safe address formats despite governance challenge

Quantum computers will inevitably reach stage 4 and become a threat to the Bitcoin network, which means that Bitcoin must implement a quantum-safe address format, the paper argues.

The measure will require the integration of post-quantum cryptography (PQC) into Bitcoin, such as the ML-DSA lattice-based signature scheme and the SLH-DSA hash-based signature. 

“Those standards give us confidence in the capabilities of post-quantum cryptography,” wrote Ark Invest, cautioning that upgrading to PQC on the consensus level will be more difficult due to Bitcoin’s decentralized governance structure, which requires the majority of network participants to agree to a soft fork.

The paper said Bitcoin will eventually need quantum-safe address formats and, over time, post-quantum cryptography. One draft path under discussion, BIP-360, proposes a Pay-to-Merkle-Root output type designed to reduce long-exposure quantum risk by removing Taproot’s key-path vulnerability, though it does not itself add post-quantum digital signatures.

However, BIP-360 is not the final solution to Bitcoin’s quantum threat, according to Chris Tam, president and head of quantum innovation at BTQ Technologies.

“The proposal introduces a new address format but critically does not include post-quantum digital signatures, which are essential for any meaningful long-term defense against quantum attacks,” he told Cointelegraph.
