There is an unbelievable amount of content out there about crypto, especially on YouTube. Everyone is trying to jump on this bandwagon and trying to make a quick bug without even knowing some of the easiest fundamentals about Cryptocurrencies. You see a lot of these younger generation youtube guys talking about lambos and which shitcoin 100x next, most of them have no idea what they are talking about. Here are some of the youtubers you wanna avoid like the plague:
JR Business (aka JR Garage), CryptoNick, Trevon James, Craig Grant (some of them adviced to invest into the obvious ponzi scheme bitconnect, which finally came to an end at 17th January 2018)

You don´t wanna be stuck watching all videos from all YouTubers, be selective about that and the time you spend on your research.
