As always subscribe to quality Youtuber who knows what's the in and out in the Cryptoverse. And admits his lack of knowledge on certain things and talks about substance on each video they produce.
A good Crypto Youtuber should connect to there audience, with humor and attitude on the topics. I recommend to follow "Doug Polk Crypto".
Stay away from CryptoNicks and Trevon James (Bitconnect Scammers)
