As most of you know, you get 40 bonus points a week at max (40gb uploaded) at Swedvdr. That is if you donīt upload requests, donate or gamble at their softbet which is the only other ways to get more than 40 points.
Those 40 points could be used to "chop off" 10gb from your amount downloaded OR -10gb from someone elses download.
At some swedish trading forums people use to offer invites for -gb at Swedvdr and vice versa.
But the question is, how much should -10gb be worth in invite tradings? Like, if you offer to chop off -50gb from someones amount downloaded for 200 bonuspoints, thatīs bonus for 5 weeks seeding. That must be worth something.
