文章里面说的这一类群组我很少去看。不过我相信群组里面大多数人还是友善的（沉默的大多数？）。只是有几个戾气比较重的人经常发言，把气氛搞得比较差。
另外在 IM 软件里面想要有高质量、长篇大论的回答是不现实的。既然没有 Stackoverflow 的回答水平，也就别要求提问者有 Stackoverflow 的提问水平。

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
