From Youtube's Adsense payment FAQ: "The AdSense payment cycle is monthly. As long as you’ve completed the steps to get paid, we’ll issue a payment between the 21st and the 26th of the month."During today's Minescam stream he said he gets paid by Youtube between the 22nd and 23rd of the month. I'll add a clip when I have more time, (probably much) later on today.
So that's an accurate statement on his part and good to know.
