If the operator of MyBitcoin is going to be found, the investigation may depend on blockchain analysis. Blockchain analysis may also indicate when the MyBitcoin coins were withdrawn - that is, whether the operator was backing deposits with real bitcoins and suddenly withdrew them, withdrew them gradually, or what. In order to figure this out, investigators will need addresses that MyBitcoin used. So if you did business with MyBitcoin, please post:
- Addresses that MyBitcoin gave you, which you sent coins to for deposits, and
- Addresses that you gave MyBitcoin, which they sent coins to for withdrawals. You can find these addresses by looking in the transaction history of your Bitcoin client.
