I come from Poland. Today on television I saw an advertisement in which they said that kryptowalut and Bitcoin is a financial pyramid. They said that in a moment the bubble would break and investors would be left without capital. It was a advertisement financed by the government and the police. Why is this happening? It is quite depressing.
On the other hand, Bitcoin ATMs appeared in hypermarkets. Strange true?

I'm having time to understand what is a kryptowalut but I figured it out kryptowalut = crypto wallet.
Don't be depressed, if your government doesn't like bitcoin that way then why they are making such statements on national television and why not just implement a nationwide ban, that's even weirder.
That's the popular call for bitcoin as a pyramid / ponzi but have they considered and look out to the fiat money? they misunderstood it because of the scammers that are using bitcoin to their scam schemes.
