Former Mine Digital CEO Accused of Misappropriating Funds The Australian Securities and Investments Commission (ASIC) has filed fraud charges against Grant Colthup, the former CEO of cryptocurrency exchange Mine Digital. Colthup is alleged to have misappropriated approximately $1.47 million AUD (at the time) worth of Bitcoin (BTC) belonging to Mine Digital customers. The charges stem from an ASIC investigation into the operations of Mine Digital, which went into liquidation in December 2022. The case will be heard in an Australian court on December 16. Mine Digital was founded in 2019 and was one of several Australian cryptocurrency exchanges that collapsed in 2022. The collapse of these exchanges has raised concerns about the regulation of the cryptocurrency industry in Australia.
