not everyone can talk about cryptocurrencies, only authorized voices should be heard.
Everyone can talk about cryptocurrencies, but the bullshit of the scammers and spammers should not be heard. Nowadays many cryptocurrency related scams are going on, and some people are falling for them. And this is bad for the reputation of cryptocurrency. But as a part of freedom of speech, everyone have the right to express their views and opinions, even if their views and opinions are outdated. The internet is open and free, and it should stay this way. No one can take away the right from no one to speak. People have to decide who and what they listen to, what they believe in.
