... because Bitcoin transactions can be traced back to you!
Bitcoin is a decentralized peer-to-peer currency, but many people mistakenly believe that Bitcoin is fully anonymous. Not so. Bitcoin transactions, by design, can by everyone.
For example, if you send a donation to WikiLeaks
For example, just use http://blockexplorer.com/ to easily view the history of a bitcoin address. Scary stuff!
Now imagine you were to buy something on an onion website like Silk Road. Your bitcoin address could be easily traced back to you, landing you in very hot water.
The main problem with Bitcoin anonymity is that every transaction is publicly logged by design. Anyone can view the flow of Bitcoins from address to address in the blockchain. This data alone cannot be used to identify you because the addresses are just random numbers, but if any of the addresses in a transaction's future or past history can be backtraced to a real identity, it may be possible to find out who owns all the other addresses. Such identity information could be derived from network analysis, surveillance, or a quick google search for the bitcoin address. YIKES!
If you buy bitcoins using an exchanger such as Dwolla or MtGox, the bitcoins you purchase can be traced back to the exchanger, which may have your real identity information on file, including banking data. Even bigger YIKES!
The moral of this story is that you absolutely MUST anonymize your bitcoins (yes, LAUNDER them) if you want to remain anonymous when using Bitcoin.
That's what we do for you.
