A significant amount of old bitcoin being moved by a whale can sometimes indicate potential selling pressure, but without knowing the whale's intentions (selling vs. redistribution), the impact is moderate. the quantum computing news is also a long-term concern rather than an immediate price driver.
The movement of old btc could lead to selling, putting downward pressure. conversely, it could also be for redistribution or simply consolidating holdings. the quantum computing threat is a longer-term concern and doesn't necessarily translate to immediate price action.
The quantum computing threat is a long-term technological risk that could affect bitcoin and other cryptocurrencies in the future, but likely not in the immediate short term. the whale movement could have a short-term impact if they decide to sell.

They moved 500 coins, which are worth more than $40 million at the current price. Besides, while Google has recently published a warning about the quantum computing threat to Bitcoin and crypto wallets in general, a message by Satoshi emerged, in which the mysterious BTC creator had already addressed that possibility. $41 million in Bitcoin on the move A CryptoQuant analyst, who goes by the name @JA_Maartun on X (formerly Twitter), published a chart showing spikes in the movements of dormant Bitcoins.

Crypto Market Review According to the chart, 100, 200 and 300 coins were moved yesterday, likely meaning that old wallets have been reactivated and their owners decided to either move the BTC to exchanges to sell or have just reshuffled their crypto holdings.

This highlights an unusual surge in activity from long-term Bitcoin holders. This could indicate a change in the behavior of old Bitcoin holders now that Bitcoin is facing selling pressure below the $70,000 price level.

In 2010, Satoshi Nakamoto gave his response to a question about Bitcoin and the rise of quantum computing “we can still transition to something stronger” pic.twitter.com/VKiVaSWUvi — Binance.US 🇺🇸 (@BinanceUS) March 31, 2026 The mysterious Bitcoin creator had foreseen such a potential threat coming from new technologies. Satoshi stated that if Bitcoin signatures were compromised, then “even agreeing about the last valid block would be worthless.” He warned that if such a threat were posed, indeed, “we can still transition to something stronger.” According to the report published by Google Quantum AI, the time and hardware requirements for hackers behind quantum computers to break blockchain encryption are much lower than was assumed before. The crypto community had been aware that eventually a moment would come when quantum computers would be able to threaten the 256-bit elliptic curve discrete logarithm problem (ECDLP-256). The latter offers strong protection to cryptocurrency wallets. However, Google proved that algorithms would require only 1,200 to 1,450 logical qubits, rather than billions of them, to make that happen. #Bitcoin #Cryptocurrency Whales #Quantum Computing
