What you might find interesting is the following :
I was posting on forums that i wanted someone to find a video or make one of the procedure of updating an altcoin wallet since it went from PoW to PoSv.
But it didn't get any attention.
But i when i posted the link below with a 2 $ bitcoin reward. even though it was small, a video was made in the same day.
https://www.reddit.com/r/potcoin/comments/3fiasl/ive_created_a_small_reward_2_if_anyone_can_make/
So bitfortip can also motivate people to upload a new information online that didn't exist before.
