As discerning dark web drug dealers and pseudonymous hackers have figured that Bitcoin is not magically private money, many have turned to Monero, a digital coin that promises a far higher degree of anonymity and untraceability baked into its design.
But one group of researchers has found that Monero's privacy protections, while better than Bitcoin's, still aren’t the cloak of invisibility they might seem. Monero is designed to mix up any given Monero "coin" with other payments, so that anyone scouring Monero's blockchain can't link it to any particular identity or previous transaction from the same source.Read more
Internet paranoiacs drawn to bitcoin have long indulged fantasies of American spies subverting the booming, controversial digital currency.
Increasingly popular among get-rich-quick speculators, bitcoin started out as a high-minded project to make financial transactions public and mathematically verifiable — while also offering discretion.

"I had seven bitcoins stolen from me through fraud," he said.Read more

Cryptocurrencies were supposed to be largely anonymous. But a software tool gives the IRS has a better chance of identifying people who hide their wealth.
You can use bitcoin. But you can’t hide from the taxman. At least, that’s the hope of the Internal Revenue Service, which has purchased specialist software to track those using bitcoin, according to a contract obtained.

The IRS has claimed that only 802 people declared bitcoin losses or profits in 2015.Read more
