Q: Why are there so many people, from high-ranking officials and expert professors to grassroots crowds, so excited and emotionally cursing when it comes to the issue of Bitcoin and cryptocurrencies?

A: There are no shortage of trolls anywhere; the most common and worthless are trolls, so let them rant. It doesn't matter to those who play; it's as if they don't exist. The trolls may occasionally see a trace of disdainful pity and sneer.
