Speed.cd is a sister site of the same owners like IPTorrents , TorrentDay , Torrenting etc ,
so you will find fairly similar content here.
It is the home of the encoding group DiVERSiTY and has a good variety of Movie/TV Packs, Games, Music and 0DAY Apps.
This is a ratio based tracker with bonus system , but with bps you can't purchase invite to invite others . Speed offers a lot of MutzNutz music packs as freeleech which will really boast your ratio quickly . As with any other trackers it is best to jump on the newer torrents if you don't want to download bigger files. They don't have IRC but they have active forum and internal chatbox.
Regarding Ratio , If your ratio drops to 0.4 or below you will no longer be able to download
In order to upload, you need to fill in upload application and get approved.
Its pretime is good but some files are not seeded properly . Invites are given on based of user class.
Donation system is available on the tracker so anyone can get the benefit of donation . This tracker theme is cool,
over all its a nice back up general tracker for you if you don't have IPT , TD or FL .
