i dont think its scam, they take really long time to pay, its been over 2 months since i cashed out but dint reveive the payment, some claim it takes up to 5-6 months, anyway dont go to invest any money in bux.to unless you feel it secure..
i can tell you is so far i see payment proof of free members those peoples has wait 6-7 month till they get there money on alert pay. I self waiting for mine payment of bux.to 3,5 month but i am premium member.
I have heard that they eventually pay but it could take several months.
I recently requested payout as well so very interested if they pay or not myself, which I will find out in a few months from now :)
