Bitcoin remained stable around $78,000 following a volatile week marked by two significant security breaches in the cryptocurrency sector. Polymarket reported that it refunded 689 of the 726 wallets affected by its recent hack, with the remaining 37 being processed for reimbursement. The breach occurred due to a compromise of a third-party provider, prompting Polymarket to pause trading and assure full compensation to affected users. Additionally, a larger hack at Binance resulted in over $6 billion stolen, attributed to North Korean actors. The FBI confirmed the operation was named 'TraderTraitor.' The overall impact saw more than $1.6 billion in leveraged bets wiped out, but markets have since calmed, with Bitcoin trading at approximately $78,000 over the weekend.
