There are some advantages to Cryptocurrency - including the obvious - you can generate it yourself. Other people like the fact that it is a little more obscure and unregulated. If you are into questionable activity - and perhaps other activity that is legitimate, but don't want the transactions traceable, Bitcoin could soon be your place of refuge. Dark Wallet is being tested where your transactions will be scrambled into segments spread around to make it almost impossible to trace. Instead of an offshore account, you'll simply need to deal with Bitcoins in your Dark Wallet.
Bitcoin works only because every transaction is recorded in a public ledger known as the blockchain, an unforgeable accounting file that’s constantly being replicated and distributed to thousands of computers running bitcoin’s software. The blockchain doesn’t identify who’s spending or receiving bitcoins with real names, only jumbled strings of characters known as bitcoin addresses. In theory, that makes the digital currency as anonymous as cash and as frictionless as PayPal.
