As one of the newer file sharing companies to come out, who knows if they’ll last long at all. No one knows. The only thing for sure is that usenet will be around long after these file hosting companies fall apart.
Anyway, turbobit is pretty reasonable with their premium subscriptions at $9 per month, and that’s all you’d really want to pay with them because they could be gone next month.
As with most file sharing services, the speeds you get might fluctuate – especially with these new file hosts that don’t know what they’re doing. If you want something “real” again, the only option is to turn to usenet. It’s decentralized so if one server goes down the others are still up. Nearly impossible for it to go away entirely.
For a guide on usenet, refer to my usenet download guide.
