Are you seriously, LimLims?
Catching rain enough to withdraw, not far from required amount to be able to withdraw, really?
I don't think that there are guys can catch enough rains like you said only days after the start of WinDice site and its rain drops.
I have also witnessed that many people are collecting the rain and are not too far away from making a withdraw from the freebies.
That's it.
Only allow to withdraw money from rain drops if deposits send first.
After that, senders can withdraw all both rain drops and deposit amount.
Moreover WinDice also need to consider that, they must allow only the withdraw if the user makes an deposit.
