On December 23, 2019, Googles YouTube.com began removing bitcoin and other cryptocurrencies related content from the video-sharing platform in whats being called a crypto-purge, leaving content creators in the bitcoin and cryptocurrency vertical unjustly attacked by the web-search conglomerate. According to Forbes, at least 35 crypto-focused YouTube channels were affected by the purge, including ChrisDunnTV, Nugget News, Crypto Tips, and BTC Sessions. More prominent publishers such as CoinTelegraph and CNBC, appear to have been spared. I have found this info here
https://techandmedialaw.com/youtube-content-creators-in-bitcoin-genre-red-flagged-was-it-an-error/ but I need more clarification, what actually happened by Youtube?.
As per my information and some youtubers review, youtube block few crypto channels and many of the big youtube crypto channels receive a strike on their channel. No one was sure what and why this happened. I do not think bitcoin channels will be removed because it will hurt not only the youtubers who are running crypto channels but also the viewers will not be happy by such acts and policies of youtube.
