yes i got paid before.
and i am waiting for the new payment.but i dont know why i have not been paid at the end of last month because i have more than 10$.

i choosed Preferred payment method : paypal($10 minimum),i feel a little confused.
Do you mean you have not got payment of January in February? I think you are supposed to request your payout at the end of the month which you might have forgotten. I don't think they will automatically pay you at the end of the month.
