ok, please tell me why I should make deposits:

Minimum savings of 500 Credits required for 6% interest every 30 days. Deposits require pending time of 1 days before interest accrues, or a 5% early withdrawal fee applies. Deposits may be moderated. Maximum savings of 10,000 Credits allowed. Transaction fee of 2% applies on all transfers.
I loose 2% with deposits
I loose 2% with withdrawl
I get 6% interest but loose 4%, so nett 2% profits monthly... that will not make me rich!!
