No offense, but it is not the coin's fault that you don't follow how CCT investbox works.
I am actually not sure either, but I did two things so far and I got paid everytime.
1. I think they are limited to a certain amount so you have to be fast when they open a new investbox to put your coins in.
2. I also think that after you got paid for the first 24 hours, you should take them out and wait for the next box to open (except with the weekly box) . If there is another box and it's has been there for a long time, you are probably too late.
