I've read a lot about the Bitcoin nodes and about running one myself but it's nearly impossible to download almost 500 GB of the entire Blockchain with the speed of the Internet I'm currently using. I know nodes are just simple computers running on the Bitcoin network operated by individuals and I've also learned that there are approximately 75k active nodes ( both listening and non-listening nodes) my curiosity is what would happen to Bitcoin if these 75k node operators decided to shut down. I know I'm thinking too much but nothing is impossible, right? I mean these are operated by humans.
