You can disable the email you use publicly as a login email.
I would recommend you look at some other guides before you do this but the gist is My Account > Your Account > Manage Account Information.
Then you can add a new email that you do not share as your primary login email, and disable login from the email you use to send emails.
It is actually true though, I only use tmux nowadays when I am SSHed into a server that I need to do some work on.
The only issues I've had with it is that sometimes it's hot keys conflict with vim, but you can easily turn it temporarily off with ctrl+ g.
If you're already used to tmux I'm not sure you would benefit much from changing, but it definitely has a better out of the box with pane hints, names, and more user friendly hot keys.
Not all companies operate like this, but many large ones do. Smaller chops can have exactly the kind of culture that you describe, but they're also quite often hard to find as they tend to have some stable business and long employee retention, it's unlikely you will find them at the same time you're looking for a job.

Say you just started working, have no use for your money and are willing to bet 20k on index funds vs a 90% market drop, you should be able to take 2k in leverage and set up your position be auto closed.
But of course as you have more money this type of market exposure starts shifting as you have shorter timer horizons to rebuild and are instead going into more of a wealth conservation mode.
Anecdotally when I moved to the Netherlands I was making 50k and over two years later 70k at that same company with about 4 years of experience.
If you look at talent.io tech report and other resources the median tech salary seems to be closer to 60k (70k Amsterdam) for all experience levels, all categories, so with some looking around you can find much better than that.
