Idk why, maybe it's because of my upload speed (only 3mB/s).
but after uploading, it works, i started to seed, after that 1 person finished, suddenly that 1 person is the one who seed to all of the people who leeched of my torrents, i NEVER seeded again after that even though my torrent client is still "seeding", there's no peer connected.

i suspect maybe someone else has more faster internet and he's the one that get more people, but this is infuriating because even though i always set my torrent to "seed" and there's people leeching, no one is connected to me so my upload ratio never goes up after the first guy, my only solution is to upload another new torrent but then it will happen again.
