i have got 0.01 BTC through signature and personal text campaign today and some thousands of satoshis through a range of good paying faucets.
400k satoshis is the only maximum payout you will got for today in your signature campaign based on your current rank.
I think what he meant was he earned 0.01 BTC overall, not only from sig and PM campaign cuz it's impossible to earn that high with his current sig campaign along with PM campaign
Anyways I've earned a good 0.06 BTC today from selling an account to a friend
He said only 3 methods (Sig campaign + PM campaign + Faucets) and no words he tell anything about other method. The word he used is "today" so he got that today.
Still possible though , 400k satoshis max payout rates from campaign + maybe around 200k?? from OM campaign and 400k in faucets.
