According to media reports, the CoinTiger exchange has been mired in money. On August 17, the CoinTiger exchange announced that the cold wallet storing PTT was stolen and lost 400 million PTT. Perhaps due to the early disclosure of the news, the PTT secondary market suffered a strong earthquake. On the 16th, PTT's biggest drop in single-day days was close to 100%, and it also fell over 70% on the 17th. It is worth noting that according to the hacker address provided by the CoinTiger exchange, 400 million PTTs have been stolen by hackers on July 1, but the stolen incident was announced on the CoinTiger exchange on August 17.
