Asked when such an underground movement could emerge onto the streets, he added: "I don't think it can work before parliament election, but it can work between parliament elections and presidential election."
The tycoon refused to rule out violence, but insisted the Kremlin would be responsible.
"It's impossible to exclude (violence) in Russia. But the responsibility for this violence is the responsibility of government, as is all the time when the people go to the streets."
"I mean force as what has happened in Ukraine, the Orange revolution, it was force because they pressed government but luckily without blood," he added.
Democratic movements staged the Orange Revolution in the former Soviet republic of Ukraine in 2004, a popular uprising that brought pro-Western President Viktor Yushchenko to power.
