Good discussion guys. I have my roth with betterment. It is a robo advisor with minimal fee. You just contribute dollar amount and forget. It auto allocates funds for your investment. I like the park and forget kind of investment when it comes to roth. There are also M1 , Fidelity, Schwab, Wealth front and lot more to choose from, but if you want automated investment that the sophisticated algorithms pick, then I would recommend Betterment.
