"Clearly I consider the Trump administration a danger to the world", he added, CNBC reported.
"I give President Trump credit for motivating his core supporters brilliantly".
However, Soros didn't stop there on the dangers of Trump's presidency.
While laying into Trump, who is also in Davos for the forum, Soros mentioned the current drama unfolding between North Korea and the US.
The billionaire investor said he expects a "landslide" win by the Democrats in the 2018 midterm elections, the Straits Times reports. "Indeed, the United States is set on a course toward nuclear war by refusing to accept that [North] Korea has become a nuclear power".
To head off a nuclear crisis, Soros recommended a "carrot and stick" approach in which North Korea is rewarded for "suspending further development of nuclear weapons".
"This creates a strong incentive for North Korea to develop its nuclear capacity with all possible speed, which in turn may induce the United States to use its nuclear superiority pre-emptively; in effect to start a nuclear war in order to prevent nuclear war".More news: Trump Grants First International Interview to Daily Mail

Most of those organizations were said to be funded by George Soros, which raised questions about whether the groups were struggling for democratic values or they were merely trying to make Trump's tenure more hard.
And he expressed worry about the European Union's future, saying that the bloc is "in a revolutionary period" where Russian Federation again has arisen and the EU is in disarray.
Soros argues there should be a change so that European Union membership should not depend on joining the euro: "I would like to see Britain remain a member of the European Union or eventually rejoin it and that couldn't happen if it meant adopting the euro".
Soros also compared the companies to casinos, saying they "deliberately engineer addiction to the services they provide".
Soros said the tech companies were a "menace" and "ever more powerful monopolies", that would be tempted to "compromise themselves" to enter the Chinese market, where they have always been banned.
But the Hungarian investor's words had no impact on the market as both companies ended Thursday's session higher, even as he accused such websites of influencing how people think and damaging democracy - "particularly the integrity of elections".
