Am I over-diversifying with multiple robos and RSPs?

For me personally. I used to invest in multiple platforms. An incident which happened to someone i know changed my decision. Im now only invested using DBS. Cause if anything were to happen to me, atleast my kids n wife dont have to crack their heads to find out where else are my investments. Its all held by DBS. Yes i do agree that fees paid are higher. But atleast im rest assure to know that if 1 day im not around. They only have to remember DBS

Couldn't have said it better myself with all the answers provided here, I have nothing more to add in terms of monetary considerations.

Maybe let me add on a little non-monetary perspective, being on so many platforms, also means you're diversifying your time and energy. If you consolidate, it would probably yield you better "returns" in other aspects of your life too!​​​
