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.
After joining the Companions and getting the quest Trouble in Skyrim where the Dragonborn has to clear out Rannveig's Fast it can be impossible to complete if it has already been cleared out before hand, this may be due to having Dawnguard installed, and having being sent to kill the vampire inside and killing Sild.
