How would you make money ?

[Nystul]

I would probably consult a professional with that much money at stake. It makes a difference whether you need access to the money in the short term or can lock into longterm investments, and of course some investments are riskier than others (and some require more personal attention than others). I wouldn't dump any more into a bank account than the amount you may need short term access to, because there are relatively risk-free, long term investments that will give higher yields than a bank account.

Of course, if you have unpaid loans, rent your residence, etc., the old-fashioned approach would be to square up those issues first and invest afterwards.
