Ionic also said its auditor, RSM US, severed ties with the miner, citing a strategic decision by the accounting firm to “disengage from all audit engagements with companies in the cryptocurrency sector.” However, RSM told CoinDesk that it will no longer audit publicly traded digital asset mining companies, but that it is not dropping the whole crypto sector. The auditor will still offer its services to privately held crypto-related firms, a spokesperson said.
