Check out Hive.io and learn as much you can about their DAPPS (Decentralized Applications) under ecosystems. There are more than just what they have partnered with on their website but its a good start. Then there are newbie threads on hive.blog and PeakD. I'm not huge on YouTube anymore but if your new to hive or crypto in general you can learn a lot from YouTube still but don't take trade advice from anyone. do your own research. Just use other peoples knowledge as a tool not gospel. (although jeff has been pretty spot on since ive followed him)
