Depends on what you want it for. You could move some to a high-interest savings account as an emergency fund, and then I'd put the rest in an index fund. At least do something where it's earning some interest.

What is the purpose of the money? If part of your retirement/long-term savings, it should be invested in a brokerage account according to your overall asset allocation.

I work for myself. Been reluctant to let go of this money (or move it) but having it sit around doing nothing is plain dumb. I am 42. Thank you.
