On etherscan, what can be said about an Ethereum address that starts with a non-zero opening balance? we would expect there to always be a blockchain trail for all transactions.
For example, at this address, the first incoming transfer of funds in ETH comes from an UNLINKED address (we normally can click all addresses on etherscan by their link and view its ledger). how is this possible? please list the different ways. Is the source of funds being concealed somehow?
