A couple of important things to remember:
1) During 'Lock' periods the VSL token cannot be moved on the network.
So, trying to send VSL tokens between addresses will not work for the lock period.
2) The ProfitContainer contract works fine. If you are having specific issues withdrawing during a lock-period then you should go to vdice.io and hit the 'Support' tab on the site. Then any specific issue you are having can be dealt with by our technical staff.

How can we know that how we will be receiving the dividend for the coins we are holding , like if i am holding 500 VSL coins then how much will i receive in dividend as if the divided is lesser then the transaction charges like (gas charges) then i think it is better not to claim the dividend
