That was deep. The manga shows the reality of trading, how it's so easy to fall into a gambler's mindset and chase money, even as far as taking debt to chase back your losses. It shows how you can't trust others in financial decisions and that everything is your responsibility. It also uses real-life events and charts such as the Lehman Brothers bankruptcy and the Swiss unlimited interventions, and various other economic news, which gives life to the story. 10/10 would recommend, I'd really love to see an anime adaptation of it, but it's too niche for that. There aren't a lot of shows about trading, and this wasa pretty unique one I've read.
