Yo guys, proudly I announce I am the winner of a freaking cool pair of bitrefill socks (yes socks) after answering a quantum-bitcoin question during a Quantum and Bitcoin event organised by Bitcoinology. It was a pleasure to attend the session given by Tracy who is the UK country manager for Bitrefill and founder of Bitprocure, a company that helps people import goods from overseas, paid for with bitcoin. I enjoyed it a lot and learned that Xpubs should not be shared not only for privacy reasons but also for quantum security (are you using hardened and non hardened derivation path for your master key? )
