Mazars Group, the accounting firm used by crypto giant Binance Holdings and other crypto exchanges for proof-of-reserves statements, has paused all work for cryptocurrency firms.
The Paris-based auditing firm said it had suspended work for cryptocurrency companies because of indications that markets have not been reassured by the “proof-of-reserves” reports it has published so far, Bloomberg reported on Saturday, citing a statement from the company.
The firm was also concerned about intense media scrutiny, the statement said.
Mazars, which was hired in November by Binance to perform a proof-of-reserves check on its Bitcoin holdings, found that the exchange's reserves on a single day in late November were over-collateralised, as per media reports.
Mazars later deleted the webpage containing a report published on December 7, on the check.
