Question:

After world war II, young Tucker tried to break in the automobile business with his original "Tucker Torpedo" automobile.(You should see the movie"Tucker") But the Big three automobile makers(GM, FORD, and CHRYSLER) formed their own exclusive club, not allowing a new comer to join the club. With a plot(bully tactic, squeeze the capital, or tarnish Torpedo's credibility), they destroyed young Tucker's dream to be a major car maker.

Suppose you are in the same position as Tucker's to break in the Oligopoly market(Big three ).

Can you give us another Cinderella company successfully breaking into Oligopoly Jungle in the past and in the near future? Do you think the industry and exchange market of crypto currency (Bitcoin, Ethereum etc.) will be Oligopoly or Monopolistic competition in coming decade? (0.5 point)
