Level 1 only 15 satoshi/minutes?
Affirmative. It was 10 times higher, but then OP lower the pay rate as there are lots of bots abusing it.
Many bots in 1 lvl. Tomorrow Fixed problem and raise earning rate.
The rate won't affect the bots.. hackers will just load more bots to compensate..
Just get good captchas services and you'll get riid of the bots..
+ keep a high payout even for free users to get more trafic (and add some ads to get additionnal revenues)
