According to a Polish news portal, the anti-crypto campaign was orchestrated by Youtube blogger from Poland, Gamellon. For this campaign, the Central Bank of Poland had spent 91,000 Zloty (about $27,000).
At the time of writing this article, this video has over 500,000 views and has not been marked as a paid promotion.
Gamellon used the hashtag #uważajnakryptowaluty, which stands for a website set up by the Polish government to warn users about cryptocurrencies. According to this site, there are several reasons on why users should be wary of cryptocurrencies.
Another blogger Planeta Faktów published a sponsored video on their channel titled ’10 Differences between money and cryptocurrency that you need to know’. It also has the same hashtag, #uważajnakryptowaluty. But unlike Gamellon ’s video, this one has an ‘Includes Paid Promotion’ tag at the start of the video.
There is no law against cryptocurrencies in Poland. But it is illegal to create sponsored content without explicitly mentioning it.
