Bitgrail, a cryptocurrency exchange specializing in trading Nano (previously Railblocks), stopped all operations after losing 17 million XRB, at that time costing about 170 million dollars. The Italian exchange suspended the input and output of XRP two weeks earlier, and customers were already afraid of the worst. The other day the operator of the exchange Francesco Firano (Francesco "The Bomber" Firano) confirmed the bad news, which caused a stormy reaction of the Nano community. Many believe that the owner of Bitgrail carried out a fraudulent operation, stealing almost 13% of the funds from the total number of tokens in circulation.
