Making up lies with the hope that it will influence behavior in the "right" way is not education and is not the way a government institution should behave.
Because unless there's an awful lot lost in machine translation, the government information website it links to might be anti-crypto slanted but is pretty bland and factual about the risks involved in crypto and its status under Polish law.
(Of course, what's easier to evaluate is the judgement of English language crypto websites like Trustnodes which attack the SEC for "effectively calling investors stupid" for having the temerity to suggest they might not be in possession of all the facts and for the "draconian" halting ICOs that were "legitimate" in every way except perhaps being precisely the sort of unlawful securities offering the SEC is tasked with shutting down. So there's a distinct possibility they just might be exaggerating a tad here)
