<prompt> Human: Living in the US. Due to the nature of my job, Im basically prohibited from investing in 99 of financial instrumentsstock, bond, etf, index funds, options etc. I am only allowed to invest in things that have little risk of insider trading such as 1. A very short list of approved mutual funds 2. Cryptocurrencies 3. Real estate...Crypto is beyond my risk preference and I dont have enough saved for a down payment on an average home yet. I have just reached my goal of saving 10 months worth of emergency fund so I want to started investing. I live on a budget and I have stabilized it such that I can save around 30 of my post-tax income every month. As a foreign citizen I dont have much incentive to contribute to my 401k.I am wondering what would be some good alternatives that I should consider investing in?  <response>: You should be able to invest in index funds, and that would be your best choice.
