On Friday the US Department of Justice indicted 12 members of Russia’s GRU intelligence agency for hacking the Hillary Clinton campaign, the Democratic National Committee, and the DCCC. The indictment alleges that the Russians partly funded their hacking operation through Bitcoin mining and conspired to launder the equivalent of $95,000 USD “through a web of transactions structured to capitalize on the perceived anonymity of cryptocurrencies such as Bitcoin,” the indictment states.

While Bitcoin and other cryptocurrencies afford users a degree of pseudonymity (users are represented by strings of numbers and characters on the public ledger), that guarantee can break down if by some means a real-life identity is correlated with an address on the blockchain.
