As for the grandparent, I think he might be in some english speaking bubble in Poland. My friends that are not IT related and are not living/working abroad are for instance not aware of the same information sources about crypto.
Internet speed ranking is some BS put there to show how Poland is behind. That could be taken out from article. But if author implies that people in Poland are so behind in technology, then they should not dabble in cryptocurrencies, and government is doing right thing.
Just this week I was explaining bitcoin to a friend. He is not frequenting english language internet, only for buying stuff from China. He knew there is bitcoin and that you can earn a lot on it. So I had to make sure that he knows buying bitcoin is buying magic beans from unknown people on internet. So this kind of campaign is good for general public. If someone is really into it, knows risks let him play. For other people, make sure they know the risks and that they can loose real money.
