Bitfinex hacker Heather Morgan (Razzlekhan) appeared at the Bitcoin 2024 conference and also attended several crypto conferences, causing curiosity and controversy among attendees. Heather Morgan hacked Bitfinex in 2016, stealing 120,000 bitcoins at the time. It is reported that Jameson Lopp, co-founder of bitcoin custody company Casa, has called for Heather Morgan to be banned from attending bitcoin conferences, but has been met with resistance within the cryptocurrency community, arguing that this practice goes against the inclusive and open spirit inherent in bitcoin culture.
