Cryptocurrencies, also digital currencies, are under the microscope as never before. On Tuesday the blockchain (区块链)supporting bitcoin (比特币)is 1 in two, as members of the bitcoin community unhappy with the digital currency’s direction set up a(n) 2 called Bitcoin Cash. However, Bitcoin Cash will likely only be worth a part of bitcoin. The original digital currency is 3 at around $2,778,39, but future values for Bitcoin Cash are just $ 288.35, or 0.103 of a bitcoin.

Last week the Russian national Alexander Vinnik, who4 cheated early adopters of millions of pounds’ worth of bitcoins, including funds obtained from the hack (非法侵入)of failed bitcoin exchange Mt Gox, was arrested in Greece.

Vinnik was described by the US Department of Justice as the operator of BTC-e, an exchange used to trade bitcoin since 2011, which was used to transfer more than $4bn for people involved in crimes.Greeek police claimed that the 38-year-old was “an internationally 5 ‘mastermind’ of a crime organistation”.

US authorities also linked him to the failure of Mt Gox, the Japan-based bitcoin exchange that 6 in 2014 after being hacked. Vinnik “obtained” funds from the hack and transferred them through BTC-e and Tradehill, another San Francisco-based exchange he owned, according to court documents.

The Russian authorities have become progressively concerned about potential for digital currencies to be used for illegal means, but remain 7 about whether it is a currency or a financial property. Elvira Nabiullina, governor of the Russian central bank, he said it should be 8 as a digital property. “We don’t consider that bitcoin can be considered as a(n) 9 currency,” she told CNBC.

But the country’s deputy finance minister, Alexey Moiseev, recently said the authorities hoped to recognise bitcoin and other cryptocurrencies as a legal financial instrument next year in a (n) 10 to handle Vinnik-style money transferring.
