Three Australian cryptocurrency mining companies went bankrupt, leaving investors out of pocket by over $104 million.

The Australian Securities and Investments Commission (ASIC) is suing these companies and their directors for alleged misconduct.

The companies promised fixed-rate returns on investments but operated without proper licenses.

ASIC is worried about investors losing digital assets and has appointed liquidators to manage the companies' cryptocurrency holdings.

ASIC warned Australians against investing their retirement savings in cryptocurrencies.

Other Australian crypto firms are also facing legal troubles due to mismanagement and regulatory issues.
