Why is it necessary to use this though there is Piratesbay or utorrent?
If there is not the merit more than these, this coin is a nothingness.
Piratesbay is a website that provides torrents links (so, it's illegal) that you can use inside uTorrent (the software is legal) to download files.
The issue for torrent clients like uTorrent is that people that make files available for others to download use their own bandwidth.
What should happen is that someone who downloads a file, should then make it available for others to download from them.
If everyone downloaded and made files available for others, uTorrent would be incredibly efficient (a swarm, using jargon).
But it's not efficient. People download, but then don't make files available.
So people stop making files available because everyone takes but doesn't give.
Instead, you have private clubs forming where people share with each other.
What.CD was an example of this.
Some private clubs charge a fee.
So you have vTorrent and JoyStream which are trying to correct this market distortion, where people take but don't give - the distortion being there are too few people prepared to just give for no return, and there are way too many takers (150m to 300m people per month)
* If you want to download from a particular person for free, no problem. As long as there are people prepared to offer files, you are good to go.
* If you want to make files available and you want to charge people, no problem. If you've just written and produced your own song, charge away, and fill your boots.
Can you see the difference? vTorrent and JoyStream are introducing a market mechanism. Payment options to give people that make files available to others (seeders) the option to charge to encourage more seeders.
People that download (leechers) can either pay to download or spend hours trying to find free content.
So the question really is why vTorrent and not JoyStream?
Well, I'm glad you asked.
* JoyStream uses Bitcoin for micro transactions. Yeah, good luck with that.
* JoyStream uses Bitcoin, which means Bitcoin transactions can be traced. Yeah, good luck with that.
* JoySream has venture capital and legally structured shareholder obligations; defacto regulated. Yeah, good luck with that.
* JoyStream doesn't have Tor or I2P, so your IP address leaks all over the place. Yeah, good luck with that.
