I also got that feeling, the author wanted to capture the plot as fast as possible and reduce the staging of the battles, I guess because of the number of episodes he was given to capture the work in anime.
Some fights were very summarized...or they arrived late to see the battles like when you watch a soccer match late.
I think that being a series that is not focused on releasing a video game and making a profit in playstation or xbox, they didn't give it an open letter to animate longer episodes, I mean this series has a social plot but not battles.
Even so it is different, maybe by being a pioneer in its genre of battles with Bitcoin and stock market, may serve as inspiration for other series that can capture it better.
