what if I wanna keep my GLIDE on C-CEX and prefer not to move. can I still get the GlideCOIN for my GLIDESEC ? or would I have to send to another wallet

I believe to get your share, they need to be on the nxt assess exchange, I guess you can then send them back afterward.
I have moved mine to the secureae and last week I got my dividend, so I have left them there
