Two things. 1. Already mentioned, you need to be connectable. Torrent client port needs opened on router admin panel. 2. You can only seed if there is another user(s) actively downloading that data. And if you’re 1 of many seeders, you’re only uploading a little bit

Theres a lot more to it but thats a good high level overview

Wasn’t dailymotion and liveleak around before YouTube? And it took YouTube some time before it became the mammoth it is now

Another comment here points out his i7-7700k isn’t supported. Its still quite capable, especially with swathes of users are only browsing the internet

YouTube was not the only platform back then but I agree it dwarfs what is around now
