I'm now with 2200 sats each 8 hours and 18 refs, not much infact but seeing the fact that I've only invested winnings from others faucets and already withdrawed 0,009 from here, well not bad...but slow slow earnings. At least they pay!
What level did you upgrade to achieve 2200 satoshis each hour?
My account with Ore-mine.org is way below that earnings per 8 hour
