Bitcoin’s ‘your keys, your coins’ promise just got an expiry date from a new developer proposal

Mythos AI threat prompts Bessent, Powell to convene bank CEOs for urgent talks

Bitcoin was built on a promise that no one can touch your coins without your private key. No government, no bank, nobody.

That promise is now, for the first time in Bitcoin’s 16-year history, being challenged from the developer community itself, as a part of measures to build defenses against future quantum computers that could compromise Bitcoin’s blockchain and steal your coins.

The proposal

Jameson Loop, one of the outspoken bitcoin contributors, and other cryptographers, have proposed a move that could force bitcoin holders to migrate their coins to new quantum-resistant addresses or face having their coins frozen permanently by the network itself. In that scenario, holders would technically still “own” the coins, but lose the ability to move them.

It is called Bitcoin Improvement Proposal (BIP)-361 and was updated in Bitcoin’s official proposal repository Tuesday with the title “Post Quantum Migration and Legacy Signature Sunset.”

This comes as a recently released Google report warned that a sufficiently powerful quantum machine could require significantly less firepower to compromise the Bitcoin blockchain than initially estimated. This prompted some observers to cite 2029 as the quantum deadline for bitcoin.

To understand the need to freeze coins, you need to know what it is protecting against.

Every Bitcoin wallet is secured by a form of cryptography called ECDSA, or Elliptic Curve Digital Signature algorithm. Think of it as a lock on your wallet. When you set up a wallet, two keys are generated: Private key, which is a unique password used to prove that you own the coins you are spending. Then there is a public key derived from the private key. This public key helps receive funds, verify transaction signatures, and ensure security without revealing the owner’s private key.

Here is the problem: your public key is revealed on the blockchain, permanently for anyone to see when you send funds. A sufficiently powerful quantum machine can use it to reverse engineer your private key and drain your funds.

As of March, the sum of all BTC in vulnerable addresses was approximately 6.7 million BTC, according to the Google study.

BIP-361 builds on the proposal put forward in February under BIP-360, which introduced a soft fork—a network upgrade—designed to enable a new transaction type called pay-to-Merkle-root (P2MR). The approach borrows from Bitcoin’s Taproot (P2TR) framework, but strips out the key-based spending path, removing an element widely viewed as exposed to potential quantum-era risks.

Three phases

The BIP 361 proposal structures the migration in three phases. The Phase A kicks in three years after potential activation, blocking anyone from sending new bitcoin to old-style, quantum-vulnerable addresses. You can still spend from these addresses, but cannot receive anything.

The Phase B, to kick in five years after activation, will render old style signatures (ECDSA and Schnorr) completely invalid such that attempts to spend from quantum-vulnerable wallets will be rejected by the network. In essence, your coins will be frozen.

Finally, Phase C, is a proposed rescue, still under research, where holder with frozen wallets could potentially prove ownership using a zero-knowledge proof, a way of proving the knowledge of a secret without revealing the secret itself. If it works, coins frozen by Phase B could be recovered.

Community backlash

The idea of freezing coins as a defense against quantum threats cuts directly against one of Bitcoin’s most fundamental promises: sovereign, permissionless control over funds.

At its core, Bitcoin is designed to ensure that whoever holds the private keys controls the coins – without exception. Introducing a mechanism that allows coins to be frozen, even under extraordinary circumstances like a quantum attack, implies that this principle can be overridden.

The community, therefore, is not happy with the proposal.

“This quantum proposal is highly authoritarian and confiscatory, but of course, it’s from Lopp. There is no good rationale for forcing the upgrade and rendering old spends invalid. Upgrade should be 100% voluntary,” one X user said.

“This reeks of central planning with the deadlines, behavior coercion, and forced migration,” another user said.

Developers, however, called it a defensive measure.

“This is not an offensive attack, rather, it is defensive: our thesis is that the Bitcoin ecosystem wishes to defend itself and its interests against those who would prefer to do nothing and allow a malicious actor to destroy both value and trust,” they said.

MSTR treasury companies emerge on STRC success

Published

on

MSTR may have paused it's BTC accumulation last week

A new class of crypto treasury companies is emerging around Strategy’s high-yield stock, STRC, drawing in firms looking to capture both exposure to bitcoin and additional income.

STRC is a security issued by Strategy, the largest publicly traded holder of bitcoin, as a funding vehicle to support its ongoing bitcoin accumulation strategy. The company raises capital by offering investors an annualized dividend of 11.5%, paid monthly in cash, with proceeds primarily used to purchase BTC.

Such is the stock’s popularity that it registered a record-breaking trading volume on Tuesday, with more than $1.6 billion in shares changing hands.

STRC, the new base layer

As trading volumes surge, a growing number of companies and decentralized finance protocols are accumulating STRC to capture its yield while gaining indirect exposure to bitcoin.

STRC is now being used as a base layer for new financial products that add leverage, tokenization and structured yield.

Saturn Credit, a bitcoin-backed yield platform, accumulated $15 million in STRC within six days of launch. Apyx, an onchain credit protocol, has built a position of 800,000 shares after purchasing an additional 200,000 STRC, with plans to become one of the largest holders.

BitStrategy is taking a similar approach. Co-founder and Head of US Ryan McGinnis said the firm aims to accumulate Strategy securities, with the long-term goal of becoming the world’s largest Strategy shareholder.

On-chain, nearly $200 million in tokenized STRC now exists on Ethereum, with close to $100 million trading on Pendle. Pendle is a decentralized finance platform that allows users to trade and separate yield from underlying assets, creating markets for future income streams.

Ex-dividend date pushes STRC below par value

During Wednesday’s pre-market trading, STRC dropped to $99.39, falling below its $100 par value, a reference price set by the company, often tied to how it issues new shares. This happened after the stock went “ex-dividend,” which means new buyers are no longer eligible to receive the upcoming dividend payment.

Because the price is now below $100, the company will temporarily stop selling new shares through its at-the-market (ATM) program.

Why is Bitcoin price falling today? (April 15)

Published

on

Bitcoin price has formed a descending triangle pattern on the daily chart.

Bitcoin price fell nearly 3% on Wednesday as investors booked profits following its sharp rally above $75,000 the previous day amid renewed hopes of U.S.-Iran peace talks. 

Summary

  • Bitcoin fell about 3% to an intraday low of $73,617 after a 7% rally the previous day, as traders took profits following the surge above $75,000.
  • Market sentiment was influenced by renewed hopes of U.S.-Iran peace talks, though geopolitical uncertainty and delays in negotiations kept volatility elevated.
  • Technical indicators remain bullish, with an ascending triangle pattern in play and key resistance near $76,000, while downside risk emerges below $72,000.

Bitcoin’s price fell today as investors booked profits following the sharp rebound yesterday. It is quite common for investors to take some profits, especially when such a sharp upside occurs after days of intense volatility amid geopolitical conflict situations.

The risk-off sentiment is not confined to Bitcoin and cryptocurrencies alone, as traditional safe-haven assets such as gold and silver have also fallen a bit today after crude oil prices moved up again following the sharp drop under $100 yesterday.

According to data from crypto.news, Bitcoin (BTC) price fell 3% to an intraday low of $73,617 on Wednesday after paring off some of its gains from the previous day when the bellwether rose 7% to nearly $76,000.

The rebound occurred amid renewed hopes of a more concrete ceasefire in place between the U.S. and Iran after reports emerged that Iran was ready to negotiate new terms regarding its nuclear program and maritime conduct.

Most recently, U.S. President Donald Trump told Fox News that the war is “close to over” after he hinted at a second round of face-to-face talks with Iran in Islamabad in the next two days. However, with Pakistan’s prime minister out of the nation till April 18, the talks could face some delays.

The diplomatic push follows after the U.S. initiated a naval blockade at the Strait of Hormuz to halt economic trade on all seaborne cargo going into and out of Iran.

The Iranian government had previously called the move state-sanctioned piracy, while they themselves implemented a controversial toll system in the area, reportedly to recoup losses for nearly $270 billion in direct and indirect damages on the nation since the start of the US-Israel war on Feb. 28.

Despite Bitcoin’s slight pullback today, its market structure continues to present a bullish bias for the coming sessions. 

On the daily chart, Bitcoin’s price action has been forming an ascending triangle which is a bullish continuation pattern if the price breaks out above the resistance level. At press time, Bitcoin’s price action was hovering closer to the upper horizontal trendline of the pattern, which suggests that a decisive move by bulls could confirm the pattern.

Technical indicators further support this bullish outlook. Notably, the MACD lines have pointed upwards while the RSI bounced back from neutral threshold to 60, showing there is still room for further appreciation before hitting overbought territory.

Hence, the next key resistance for Bitcoin lies at $76,000. A break above the trendline could trigger a rally toward the $80,000 mark.

On the contrary, if Bitcoin price were to fall below $72,000, it could invalidate the current bullish setup and lead to a retest of support near $70,000.

SocGen-FORGE Brings MiCA-compliant USD Stablecoin to MetaMask

Societe Generale-FORGE, the digital asset arm of French banking giant Societe Generale, has integrated its Markets in Crypto Assets Regulation (MiCA)-compliant USD CoinVertible (USDCV) stablecoin into MetaMask, giving the wallet’s millions of users access to a regulated dollar token issued by a major European bank.

The company said in a release on Wednesday that under the partnership with Consensys, USDCV, which is backed by cash and cash-equivalent reserves and issued under French electronic money regulations, will be surfaced in MetaMask on mobile and web. The token is redeemable 1:1 in dollars and will be made available for functions including trading, decentralized finance interaction and fiat on-ramping, with Transak serving as the on-ramp provider.

The move expands access to one of the few dollar stablecoins issued by a major European bank. It also comes as regulated issuers seek to turn MiCA compliance into a commercial advantage by distributing tokens across widely used crypto platforms. SG-FORGE CEO Jean-Marc Stenger said the MetaMask rollout is intended to broaden access to compliant digital assets.

Under the European Union’s new framework, a growing but still relatively small pool of approved stablecoin issuers, with around 10 entities authorized so far, is competing for market share, making integrations with wallets like MetaMask increasingly important.

SG-FORGE expands multichain stablecoin strategy

SG-FORGE also issues EUR CoinVertible, a MiCA-compliant euro stablecoin first launched on Ethereum (ETH) in 2023. The token has since expanded as part of a multichain strategy to Solana, the XRP Ledger and Stellar, while USDCV is available on Ethereum and Solana and listed through several exchanges and partners, according to SG-FORGE.

The euro-denominated token has been part of broader efforts by Societe Generale-FORGE to test tokenized financial infrastructure, including participation in experiments involving tokenized bonds and settlement through blockchain networks.
