Investigate crimes involving cryptocurrencies and other blockchain technologies

Bitcoin has traditionally been the payment system of choice for a criminal trading on the Dark Web, and now many other blockchain cryptocurrencies are entering the mainstream as traders are accepting them from low-end investors putting their money into the market.

* Set up and run cryptocurrency accounts
* Build information about specific addresses
* Access raw data on blockchain ledgers
* Identify users of cryptocurrencies
* Extracting cryptocurrency data from live and imaged computers
* Following the money

With nearly [...] billion in cryptocurrency circulating and $3 billion changing hands daily, crimes committed with or paid for with digital cash are a serious business. Luckily, Investigating Cryptocurrencies Forensics shows you how to detect it and, more importantly, stop it in its tracks.
