"The Destination Tag Victim"

This is a specific tragedy for users of centralized exchanges (CEX). When sending coins like XRP, EOS, or BNB to an exchange, they forget to include the "Memo" or "Destination Tag". The result? Their money is successfully sent to the exchange's main wallet, but it doesn't appear in their account balance. They spend months begging Customer Service to track their transaction in a pile of data from millions of other users.
