There's a mountain of greed manifesting itself in the market  according to  Federated Investors portfolio manager Steve Chiavarone .
But  he  says you won't find it in stocks â it's in cryptocurrencies.
Bitcoin is such a contentious emerging asset   Chiavarone  recently felt compelled to publish a market memo on it  because  he  was fielding so many questions from clients and advisors.
"Investors wanted to be on the roller coaster in the '90s. They wanted high returns. They didn't mind volatility  " Chiavarone  said.
 Chiavarone  who is a bull on the actual blockchain technology   believes there's a good chance bitcoin will suffer the same fate as Pets.com â one of the biggest dotcom bubble busts of the high-flying 90s  before tech stocks crashed.

In barely a month since North Korean leader Kim Jong Un surprised the world and said his nation was ready to join the Games  South Korean President Moon Jae-in has delayed military exercises  feted Kimâs sister at the Pyeongchang Olympics and given conditional consent to a bilateral summit in the North.
âIts delegation and athletes are getting all the spotlight  and Kim Jong Unâs sister is showing elegant smiles before the South Korean public and the world. Even for a moment  it appears to be a normal state.â
Pence cast one of the loneliest figures at the opening event. He remained seated when the joint Korean team entered the stadium  in contrast to Moon who stood along with Kim Jong Unâs younger sister  Kim Yo Jong  to applaud.

After years of ineffective implementation  those sanctions may have begun to finally bite  which  according to a Japanese government official and experts  helps explain why  Kim Jong Un  agreed to send a national team and  his  sister to the Olympics.
