This article didn't mention it specifically, but Betterment already put in a rate hike. You used to be able to get 10 basis points if you had over 100k and they just increased that to 25 in a really underhanded way. I had been using Betterment for about 2 years when they did this. I had been happy with Betterment but it's clear that they want to get as many people in under the low rates and slowly increase it on you,…
I think these companies (Betterment, WealthFront, etc) are struggling with really high customer acquisition costs that take quite a while to break even on. I'm sure that not many people noticed/cared enough to transfer out (I'm doing it now, it isn't a small task), so they came out way ahead on it.
Unfortunately, I think it will be easy for them in a year or two, when they need more quick revenue, to look back and say "Hey, not many people said anything when we raised fees by 67%, what's another 10 bps or so?"
