Per the advice above, the cost of Betterment is not worth it and will drag performance over time vs simple total market index funds at one of the big firms. ETrade, TDAmeritrade can be added to the list, and will pay you cash to open a new account if you have some money to start with.
Betterment wont spot you $2500 cash to deposit $1M, they will charge you that every year! ETrade, Schwab, Fidelity will pay you to open an account. Just google broker bonuses.
Then dont buy any of their services, just buy a total market ETF. Set it on auto reinvest. The web site will be just as entertaining with information and charts as Betterment, but for free. You will get to download statements, auto import into tubotax, etc, plus even get free seminars with food or coffee at their physical locations, if you need to deposit a check or get one issued or have free time to listen to investor information (I get free wires, from Schwab...etc.). Ive tried all the brokers and they are all fine. I like Schwabs service, but bonuses have been smaller lately.
That said, it is better that a bad broker who churns your money, if you need some investing complexity in you life. TLH does not require technology, just the ability to notice your funds dropped below purchase price, which btw you hope you never benefit from anyway.
