One Word: SeedBox
Some people object by claiming "a seedbox is too expensive". Really? Do you know how much electricity your computer uses? Then there is your ISP bandwidth usage allocation. Not to mention the general wear and tear on your computer. Running a home computer 24/7 will shorten it's life.
It's possible to get a quality seedbox with lots of extras like your own personal cloud, backup and video/audio streaming for $0.59 per day. So how does that compare?
When talking about math(s) most peeps say "I don't understand math(s)" click their brain does dead. But it's important you understand how your electricity bill is calculated.
So, here's an example. A computer that uses 500W. That 500 watts per hour, or 0.5Kwh (500 / 1000). Leave it running for a day (24 hours) that's 500 * 24 = 12,000w or 500 / 1000 * 24 = 12Kwh. And if your electricity supplier charges $0.05 per Kwh, your computer cost you 500 / 1000 * 24 * 0.05 = $0.60 per day.
So your computer costs you $0.60 to run for a day and the seedbox costs you $0.59. Which is more expensive: $0.60 or $0.59? And remember, that doesn't include the cost of replacing your computer when components stops working properly because it's been running 24/7.
A seedbox will reduce you uploading bandwidth usage. And add a layer of security by making it more difficult for others to easily see what you're doing.
Some peeps feel using a seedbox is selfish as it makes life difficult for those who can't. But you can adjust your seedbox so it doesn't cause problems for others. You can easily limit the seeding speed and configure the box to automatically stop/delete the torrent once you've reach 1:1 ratio.
Because seedboxes come with a generous about of disc space, you're able to leave torrents seeding for as long as it takes to reach 1:1 ratio. So not only are you being a nice person by seeding for a long time, you're also collecting seeding bonus.
