I don't see it as a game since there is a lot of money involved. I dont really play with my money so yeah.
Same with my opinion, I see trading as a serious matter and not just a fun and definitely not a game. There's money involved, so you take it seriously. If you will not take it seriously, it will be your loss and you may regret it someday.
I can bet my all bugs on this that no one takes trading as a fun or trade with coins because it feels like gaming. Trading cannot be done without good knowledge of coins in a successful manner. Whosoever takes it serious work hard to understand graphs in a good way and make wise moves at right time? In short, as you said trading deals with money ultimately so no one is going to take it light in any way.
