But pay varies between 100 to 500 satoshi for every submit which is limited to once an hour, so unless your time is worth nothing and you can enter a captcha every hour this isn't worth your time. On top of this you need 5500 satoshi earned to execute a payout.
This unmarked mission is one of the biggest challenges offered by Skyrim: Dragonborn. Its course is rather untypical-firstly you have to go to the Glacial Cave in the north and obtain Karstaag's skull (you will have to defeat three Rieklings on your way). It's the easiest part of the mission.
An Offering to the God. At the shrine, speak to Vajhira, and say you are a hunter. Telling her that you are prey will not have any repercussions, you may just speak to her again and say you are a hunter. She tells you to make an offer of a Bear or Wolf Pelt to the shrine. You also need to be level 17 to make the offer. Just search in any direction from the shrine for a Wolf (easy) or a Bear. Once you have a pelt, return to the shrine. Hircine will tell you to bring him the horn of the only Unicorn in Cyrodiil.
