Some Altcoins more Popular with Cybercriminals

Bitcoin is well-entrenched as the preferred payment for cybercriminals like the WannaCry hackers who have hit more than 300,000 computers over the past week, but cryptocurrencies offering more anonymity are threatening to displace it.
A key reason for bitcoin’s dominance in the nefarious online underworld, say technologists and cybercrime experts, is its size – the total value of all bitcoins in circulation is more than twice that of the nearest of hundreds of rivals.
That makes it easy for victims to access enough to pay the ransoms demanded, and for hackers to cash out of it via online exchanges to spend money in the real world.
