RoboAdvisers from my experience are very good, however that is with a caveat that over the last 10 years it would be near impossible to not make money buying broad based industry ETFs. I was an early user of Betterment in the US and they took care of all the tax calculations and calculated efficient disposals to limit tax.
The biggest benefit I have found is the relative simplicity, it basically involves setting a portfolio risk weighting, set up a direct debit and then monitor. The time I save vs manual portfolio tracking is worth it in my opinion. I have only been using ETFmatic for the less than a year since relocating back to Ireland and whilst it is not perfect I do feel it is the way of the future.
Anyone have a recent experience with it?
