On the other hand, after 2 months of clicking, I reached 30k satoshis, requested a fast withdrawal as usual, and now it's 'in review'—I have to wait at least 24 hours. It's really hard for me to reach 30k since I don't even have a referral... It doesn't change much for me, and I'll wait (and hope), but why don't they just remove the fast withdrawal option if it never works?
Not all withdrawals are flagged to be reviewed manaully and it's not that instant withdrawals never work.
I have made many withdrawals from freebitco and only one of my withdrawals was flagged to be reviwed manully.
If your withdrawal is flagged for manual review, you have to wait until they review your withdrawal and it doesn't matter whether you requested a slow withdrawal or an instant withdrawal.
