There is to high minimum and maximum deposits. Minimum 0.05 deposit prevents lots and lots of people to deposit and maximum of 0.5 is to high that makes lots of time of pending till people get payed.
Lots of people complain for pendings and thats for some people get to greedy and deposit 0.5 that is delay other people payments.
Now if you want more and more deposits low the minimum at least at 0.01. Lots of people deposits after that and the payments there will be sooner.
People afraid to deposit cause the lots of pending payments.
