I think that for this you need to be a good trader, cause trading is the most safe way to get money but i don't know, maybe you will find a good opportunity to invest.
$100,000 is a lot of money and entering it in the trading market is super risky and even if you are a good trader it still means you are taking a lot of risks which are not good for that amount of money.
with that much you should start a business of your own and start making money from working on that yourself.
