Cryptocurrency investors have grown more cautious about who they do business with, after being burned last year by sudden collapses of Celsius Network, Voyager Digital, FTX and others, and fearing a regulatory crackdown will put more pressure on remaining firms. The recent crypto platform bankruptcies trapped customer assets now worth around $34 billion, according to Xclaim, which allows creditors to trade such claims. To protect themselves, institutional crypto investors are switching to exchanges that offer stronger asset protection, boosting due diligence on trading partners, and executing trades in smaller chunks, among other new risk management measures, according to executives and industry data.
