The cryptocurrency address could be generated very randomly, which means the thief can generate a lot of addresses to transfer the money, and the old address is just dumped and will be never used again. Unless, you are using some coins are not totally decentralized, which is more easy to track the trace.
The coins that were stolen from me are still in this address. ARDOR-HKCS-V6N8-FH7T-A3SLF If they move I will follow them. They are colored. That means they are stolen. I have alerted every exchange that trades ARDR. Also I will not be using ARDR any more. That is the saddest part as I really had high hopes for this coin, but I am not going to pay network fees that support's criminals who steal other people's coins. Beyond that, I don't know what else to do.
