Idk, I really don't understand the surprised tone of all the comments. It seems very much like a cognitive distortion to believe that somewhere in financial industry there are clever and professional people doing things in a very adult and responsible way. Especially not texting about committing million dollar crimes (or just moving millions legally) in the same language as discussing memes in Discord with friends.
If you believe people must be responsible and professional just because they handle a lot of money, it's your problem, not theirs.
