Staked ETH Hits 31% of Supply, Citi Says Bitcoin Faces Larger Quantum Risk
Bitcoin‘s structural exposure stems from an estimated 6.7 to 7 million coins parked in addresses where public keys are already visible on-chain, including roughly one million attributed to the network’s pseudonymous creator. A sufficiently capable quantum machine could theoretically derive private keys from those exposed outputs and redirect funds. Ethereum is not immune; the analysts noted that a quantum-enabled adversary could in principle accumulate enough private keys to control about 33% of staked Ether, enough to disrupt block finality. Yet the relative ease of pushing protocol changes through Ethereums consensus mechanism gives developers more runway to harden defenses preemptively. Spot Ether trades near $2,124, holding marginally above the immediate $2,121 support with the next defensive zone at $2,053 and a deeper line at $1,942. Resistance is stacked at $2,131, $2,236, and $2,321, framing a tight near-term battle just overhead. The relative strength index at 35 sits close to oversold territory while MACD remains bearish, consistent with the broader downtrend and lingering bear market tone. A reclaim of $2,131 on expanding volume would open room toward $2,236; failure to defend $2,121 risks a flush to $1,942 and would invalidate any near-term recovery thesis built on this weeks accumulation signal.
