No compounding on MyBrowserCash - Can't transfer funds

Here is the reply from MBC when I ask them why I can't transfer funds from Account Balance to Purchase Balance:

Starting October 1st, only your click earnings are available for transfer.
Rental earnings can not be transferred and used to buy more refs (no compounding). Rental earnings can only be put for withdrawal.

Tech are working on adding separate amounts for click and rental earnings.

Thanks,

Best regards,

That means MBC is going to limit the RR to rent is 1RR/month or 1RR/2 month or more because the Click Earning is very low. And their payment system is very slow, so maybe people will leave MBC because of the slow earning & delay payment. Hope MBC rethink & don't do that!!!
