The Karnataka Congress, which addressed a press conference Wednesday on the alleged Bitcoin scam, has released video footage of a purported intelligence officer present during the presser. The Congress has accused the ruling BJP of double standards and questioned why there was an intel officer at its news briefing. The Congress and the BJP have been levelling allegations against each other after Central Crime Branch officials seized bitcoins worth Rs 9 crore from a city-based hacker, who is also accused of hacking into government portals.
