For me: Cancelling paid subscriptions should be as easy as subscribing. I hate the fact that they actively hide the unsubscribe option or that you sometimes should have to write an e-mail if you want to unsubscribe.
Fiat currency like the US dollar is just as intrinsically worthless. It has value only because people accept that it does, they trade with it, and it has legal status as tender "for all debts, public and private".
People trade bitcoin and other cryptocurrencies for goods all the time, without converting it to USD or anything first. I mean, yeah, usually the thing they're buying is drugs or something but it's the same as handing your local dealer a $20 bill.
You’re printing the promise of money using your actual money to pay an increased electric bill. Assuming you don’t get scammed, forget your pass, lose your key, etc.
Also destroying the planet for literally no reason (particularly PoW coins like Bitcoin) because difficulty is completely artificial. It’s what makes mining so absurd - the more miners, the more power/silicon wasted, but the output is exactly the same because the release rate is set. More adoption = less efficiency. It’s completely back asswards.
I mean, artisanal gold mining is still a huge thing in certain less-than-awesome areas. The basic way gold works is what inspired it in the first place.
torrenting is faster than usual downloading, its actually an incredible technology. i dont know the exact percentage of how much faster, but it makes sense that it would be because it puts less load on the server with the file because everyone downloading it is also sending it to each other
Torrenting can be faster than normal downloads. A file server with a fast connection that's not overloaded can easily be faster than a P2P download that doesn't have very many peers, or the peers all have slow connections. There's no fixed percentage speed boost that you get, because sometimes you don't.
That said, for things like Linux ISOs or archives of stuff that people just keep seeding forever but aren't hosted on fast file servers (if at all), it's great and typically the bottleneck is your own connection.
