- Blockchain (blockchain.info)
This website allows search of a Bitcoin address and displays the number of transactions, total amount of Bitcoin received (S), final balance, and a complete transaction history. We can track every incoming and outgoing payment. This will almost never be associated with any real names, but it provides a great level of detail about the account.
- Bitcoin Who's Who (bitcoinwhoswho.com)
This service provides a bit more analysis about the suspect account.
We can see transaction IP addresses, which are likely behind VPNs. Overall, use Blockchain for transaction details and Bitcoin Who's Who to get a better idea of why I might care about the account.
- BlockChair (blockchair.com)
This service is very similar to Blockchain, but I find it has better representation across multiple virtual currencies.
The results are typical, and include balance and transaction data.
- Bitcoin Abuse (bitcoinabuse.com)
It notifies you if others have reported a target vittual currency address as associated with malicious activity.
The results include a summary of the activity and the email addresses sending malicious email.
- Wallet Explorer (walletexplorer.com)
Many people possess numerous addresses and store them all within a virtual wallet.
While researching one of our target Bitcoin addresses within this free service, the results identified a wallet of "00037fd441" which contained the target address. Clicking on the link to this wallet revealed multiple new transactions from additional Bitcoin addresses previously unknown. This step is vital in order to track all transactions associated with your suspect.
