Bitcoin shows a more constructive signal: large holders sell less, while miners are still slowing their sales despite increasing pressure.
Long confined to speculation about bitcoin, quantum computing is now entering a much more sensitive field: that of encrypted messaging. Behind the debate on blockchain security, another more immediate threat is emerging: that of private data intercepted today, then decrypted tomorrow. Researchers and industry warn about this shift, which moves the front line towards tools like Signal or Threema.
The rapid rise of quantum computing revives fears of massive bitcoin hacking. Indeed, Microsoft’s revelation of its Majorana 1 chip, potentially capable of reaching one million qubits, fueled speculation about the end of the inviolability of private keys. However, Graham Cooke, former Google executive and now CEO of Brava Labs, dismisses these concerns. According to him, bitcoin cryptography remains out of reach, even for the most advanced machines.
