Wallets linked to the $387.5 million Bitget exploit transferred approximately $3.9 million in Zcash into Zcash's privacy payment system, Ironwood, on Wednesday, making the stolen funds harder to trace, CoinDesk reported. Transaction records show that 2,746 ZEC were moved into Ironwood in three separate transactions between 08:15 and 08:46 UTC on Wednesday. These funds represent about 15% of the total stolen ZEC. Zcash's privacy pool allows senders, receivers, and amounts to be hidden, but investigators can still see the amount entering the privacy pool.
