A couple million of profits from trading doesn't translate to a couple of million in your retirement account, with all taxes paid.
After taxes and after paying for living expenses for MB and family for the last 3 years, $2M could easily be around half-a-million. Depending on where they live, that might be more like a downpayment on a house rather than a funded retirement.
First of all, taxes will be what, a quarter or a third of it. So ok, north of 1M, still enough to retire. Second of all, if you bring in more than a million and spend most of it, down to 500k, in 3 years, then that's on you..
If most of those hit in one year and as short term gains (which algo trading will be), taxes in my state would be around 12% and federally would be around 35%. You're down to just over a million. Paying yourself a salary means 15.3% on whatever your salary is for FICA/Medicare. For a $130K salary for each of 3 years, that's another $60K, taking you to right at a million before you've spent a dime on anything except taxes. Your first box of ramen makes you not a millionaire.
Because it is boring. I'm not ready to retirement. It doesn't make sense. Maybe start my own start up would be something interesting. But right now love to gain some more skills, see what cool stuff I can learn and get rid of responsibility.
Ok, in that case I would strongly advise against advertising your net worth with your prospective new employer because they probably aren't going to hire you if they are aware of the fact that you are doing it just so you're not bored. Try to be as normal as possible if you want to get hired. What you could do is find a way to show your capabilities without directly revealing your net worth, even though I don't know what that would be. Another option is to turn some of your money into a small investment fund and to manage that. It's anything but boring.
In this context "kind of high" might be only a couple of million in profits. Enough to not want people to know, but not enough to retire on.
