Put 100,000 in a bank high interest paying bank account/product. Say 1%.
Use the 1000$ as a stop loss and trade(only if you know how) stocks. Or buy stocks and write calls.
Generate decent returns which will turn your money to double in a decent time frame.
You cannot get good return putting your money in the bank as bank is only good for savings not investing. I would rather advise you to put a lending business and offer an interest like 3% to 5% per month with a shorter term so you can roll your capital. I have seen many people getting rich in lending.
I saw some people who get rich on lending business but its quite risky for me but you must try and take the risk in able to earn profits and could able to grow your money. Just make sure that you would strictly imposing rules regarding when someones intend to take a loan.
