AFAIK, any deposit address that belongs to the exchange site would be automatically send the amounts to the exchange's hot wallet. The better if you can at least provide the addy. I think that we may also be able to help you to track it. You can track it by yourself.
If you were not seeing it being sent to the exchange site's hotwallet and im guessing if it's still on the personal wallet. It likes when you send money to the desposit address and this addy will send money deposited to the deposit address to the hotwallet of exchange site.
If you were not seeing any then we can assume if it still stays at the scammer's wallet.
The scammer's address is :
I'm not aware if a country do have their own special wallets that's only used by them which other countries can't be made use of. Op I don't also know how you knew the scammers used an exchange wallet because it's as much possible that this scammers would use a decentralized wallet instead of a centralized wallet to do their shits in other to stay untraceable due to centralized exchange KYCs.
Yeah that's why just in case if he transfer to local exchange. But looks like the scammer still keeping it on his personal wallet.
