TL;DR:
- Three “Satoshi-era” wallets transferred batches of 100, 200, and 300 BTC after 10 years of inactivity, totaling a market value of over $41 million.
- CryptoQuant analysts identified unusual spikes in the Spent Output Age Bands indicator, signaling potential profit-taking near the $70,000 resistance level.
- Google warns of quantum computing risks to ECDLP-256 encryption, while the community retrieves Satoshi Nakamoto’s archives proposing technical solutions.
A group of dormant Bitcoin whales has come back to life after a decade of lethargy, mobilizing more than 600 BTC. These major investors awakened in a context of high volatility, appearing to readjust their positions amidst selling pressure in global markets.
And another 500 BTC on the move after 10+ years

The Spent Output Age Bands chart displayed three massive green spikes in the “10+ years” category. With the Bitcoin price hovering near critical supports, the volume of these transfers suggests that institutional investors or industry “OGs” are moving out of their passive accumulation phase.
Satoshi Nakamoto and the Quantum Threat
Beyond whale activity, the crypto ecosystem has reacted to a report from Google Quantum AI. The tech giant claims that only between 1,200 and 1,450 logical qubits would be needed to compromise the encryption of current wallets—a figure significantly lower than previous estimates of billions.
In this context, the community has resurfaced a historical message from Satoshi Nakamoto on BitcoinTalk. Sixteen years ago, the protocol’s creator already anticipated this possibility, asserting that if signatures were compromised, the network could transition to much more robust and resistant cryptographic algorithms.
As quantum hardware evolves, Bitcoin’s infrastructure is preparing for upgrades to ensure long-term security. For now, the movement of these whales underscores that, despite future threats, the current value of the network continues to incentivize long-term holders to actively manage their assets.
The reactivation of ancient capital and the debate over quantum security mark a week of reflection on the maturity and resilience of the Bitcoin ecosystem.
