is it normal to keep funds split across a few different exchanges?

been doing this for about a year now and i still second-guess myself. i've got the bulk of my holdings on Coinbase, but i also keep smaller amounts on a couple of others — i use BitMart for some of the lower-cap pairs i can't find elsewhere, and Kraken for the more liquid stuff. feels a bit scattered honestly, especially when i have to track prices across three apps. i know some people swear by keeping everything in one place for simplicity, but i also worry about having too much exposure on a single platform. curious how others handle this — do you stick to one exchange or split things up, and if you split, how do you decide where to put what?
