[Zhao Changpeng Pays Tribute to BitMEX: Pioneered 100x Leverage in 2014, Multiple Mechanisms to Prevent Hacks] Foresight News reports that Binance founder Zhao Changpeng posted a tribute to BitMEX, acknowledging that as early as 2014, it was the first in the cryptocurrency space to introduce 100x leverage contract trading. BitMEX also adopted mechanisms such as supporting only Bitcoin deposits, operating on a single chain, limiting withdrawals to once per day, and managing funds through multi-signature wallets. These restrictions helped it avoid hacker attacks. Zhao Changpeng also mentioned that the four founders of BitMEX were previously accused of violating the Bank Secrecy Act. They pleaded guilty one month before the trial, each receiving a $10 million fine and being placed under house arrest. None were sentenced to prison, but the company's business ultimately failed to continue under what they described as regulatory pressure.
