can you please explain to me what's their connection between cryptocurrencies and torrents? I know that both p2p
there is no connection between cryptocurrencies and torrents. there is more of a similarity. because both of them are based on a decentralized network of computers (peers) connecting to each other and sharing a file (any file in torrent and the blockchain in cryptocurrencies) between each other. every computer can be a server and a client at the same time.
there are of course lots of differences, like for example the way peers find each other (torrent: through a tracker, bitcoin: through each other).
I also know that many countries see torrent downloads as a bad thing and have laws against it.
i do not know any country that has a law against "torrent". however they have lots of laws against "pirating".
it is like saying using a knife is illegal because it can be a murder weapon!
