Quip Network Launches Fork-Free Post-Quantum Wallet as Bitcoin Holds $77,750

Bitcoin trades steadily near $77,750 as Postquant Labs launches Quip Network's Layer-2 post-quantum wallet on April 29, using WOTS+ signatures without forking the protocol. The story ignited April 16 with BIP-361 proposals to freeze ~1.7M vulnerable BTC ($145B), escalated via Google's April 27 paper on 9-minute mempool thefts and a debunked April 24 15-bit ECC bounty win criticized as random noise by Adam Back and Google researcher Craig Gidney. Markets shrugged off risks with 10k-30k daily flows, ETF inflows, and Polymarket odds near zero for sub-$68K drops.
