If you are unsure about where you are using and want to change then just change it, there is no reason to ask others about it. Consistently using the same exchange people like what they are doing and this is why they are not changing it, personal reasons basically, there is nothing they want to change to, if you are not sure and don't want to use the same place then you have the freedom to use another exchange after a while, just like they have the right to keep the same place as well.

I believe the best thing you can do in this case would be just focusing on what you can do with your own personal investments and ignore what others do with it. Just because you have something big or small, doesn't mean it will be different.
