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.
No Stone Unturned is a quest available in The Elder Scrolls V: Skyrim. Find an Unusual Gem. Bring the gem to Maul. If already a member of the Thieves Guild, skip to Step 3. The Dragonborn must bring an Unusual Gem to Vex in the Thieves Guild, who will explain that it is one of the Stones of Barenziah. She will also say that it is not worth much by itself, and that there are 24 of these stones. Collect any remaining stones and return to Vex.
