I am curious myself. I can't answer this question for you, as you would need to ask the investors themselves. The stock price seems to move of its own volition, in ways that I cannot predict. I can only put this down to the over-exuberance of investors. It is still valued at approximately 0.6 btc, which is 3x my IPO price.
Not everyone has access to private torrent trackers that can max out their download pipe. Others may have limited or expensive bandwidth and cannot afford a 1:1 seeding ratio, which is required of you on these sites. Tor is too slow for anonymity purposes. Some people cannot use torrents because they are behind firewalls or other restrictions that throttle their download speeds. Others simply want streaming access to video files after a few minutes, while some use to service because they value their anonymity. There are many different useage-scenarios, I am not going to reiterate them. If you can't see the utility of the service, fair enough. Others do however.
I did not say that the service can provide faster speeds than the home user's maximum download speed, what I did say however is that the torrent will download up to 100x faster than it would on a home connection, meaning the file is available for instant streaming access (e.g. to vlc) or instant download access within minutes.
When you download a torrent at home, you have to wait for 100% completion before you can access it. Even with fast download speeds, this can sometimes take a long time. This service will download it for you in a matter of minutes, and it is then instantly available to access from the server. You can then stream it to your computer if it is a media file, or use a download accelerator to ensure that you max out your download bandwidth - you cannot always achieve this with public torrents, even well seeded ones.
Yes, you can give a link from a private torrent site, as long as the tracker allows torrent downloads from IP addresses other than that used to login to the site itself. If not, you can just download the .torrent file and upload it. Please note however that this service is not intended to be used as a seedbox or long term storage of files, so I cannot guarantee that your torrent will be seeded according to the rules of the particular private torrent tracker you are using.
And don't forget, not every torrent is illegal! There are many legitimate uses of the technology. Bitcointorrentz does not condone the use of the service for the downloading of copyrighted or illegal materials. So if you want to download illegal files, please feel free to do so using your own home connection, and suffer the consequences should your ISP or a IP rights organization find out about it.
Anyway, as I said, If you can't see the utility of the service you obviously have no need for it. On the other hand, If you DO have a need for the service, for whatever reason, the utility is immediately obvious. Clearly you don't need it, but thank you for your input nonetheless.
