It was revealed that there had been a vulnerability and a fraud incident. Over 500 BTC was stolen by an anonymous attacker. I moved my BTC from my Coldcard. It is really insane. Such an incident could harm the value and reputation of Bitcoin itself. AI and LLMs have been making a massive impact on the crypto industry. I visited Cafe Yamaneko in the evening. I met Tagawa-san for the first time in a long time. I also met several new people. One of the customers was from Rwanda. He said that he is not good with hot weather.
