However, he said that there are some prerequisites to that with the help of which the zero circulation of black money can be achieved. Talking about the same, Bejoy told IANS: 'I don't think it's impossible to curb black money though it's a worldwide network. With clear systems, right intentions and correct people in place, the circulation of black money can be completely stopped and there have been efforts in the past to do that as well.' Actor Avinash Tiwary, who essays the lead role of IB officer Ritwik Mukherjee in Bejoy's 'Kaala', chipped in as he said that we are heading in that direction of stopping the black money.

When everything becomes digital it will become very difficult for the operators to hide the black money because of the digital footprint and the ease of tracking the money.'
