I recently become interested in wealthfront, and plan to make the first real investment in my life. However, as I read more about mutual funds and ETFs, I realize that wealthfront is actually built upon on vanguard's mutual funds and ETFs.
The fees of wealthfront is higher than vanguard's mutual funds and ETF. Then I get a question: why pay more if I can buy from vanguard directly.
I find one answer to that wealthfront is more tax efficient. But this seems a minor reason to me. The other answer is that the minimum investment of wealthfront is smaller. I actually don't care about that.
Then what's the real advantage of wealthfront over vanguard?
