Bitcoin, a wonderful creation of this century has two faces. One which is helping the unbanked and underbanked across the world gain access to financial services by making money transfer and transactions affordable and another on the dark side being the most favoured currency among the criminal kind.
Gone were the days when criminals demanded hard cash or a wire transfer to some offshore bank account outside the jurisdiction of the country they were operating in. They have graduated, become savvy enough to demand bitcoins instead.
Why bitcoins? Because it is easier to move bitcoin than hard cash and the transactions are pseudonymous (Some still think it is completely anonymous). Going back a couple of years, we can see the adoption of bitcoin growing among the criminal community.
Bitcoin to cybercriminals is like a candy to a kid, there are many instances of cyber hacking where the hackers have either stolen bitcoins or demanded bitcoins as ransom. Starting with recent ransomware attacks where the hackers infected hundreds of thousands of computers across the world, encrypting data on these computers. These cybercriminals demanded ransom in bitcoins from the victims to let them regain access to their own data. Not even police departments were spared
