There’s a $1 minimum payout threshold in place. While it’s possible to make payments below $1, payment methods take on average 2% + transaction fee so you’d basically be left with nothing!
As soon as you make above $1, your withdraw button will appear under the “Earnings” section of your dashboard.
Note: Wire Transfers come with a different minimum payout threshold. You should have at least $500 in your available balance before a Wire Transfer will be sent. There's also a $40 fee for a Wire Transfer.
