You know there are really lots e.g Datadash, BiteSizeBitcoim, Crypto Hedge, Crypto Daily etc. etc. etc. It would be a hassle if you will try to subscribe at lots of channels just to learn information about cryptos.
To be specific, you can directly browse Youtube on what information about cryptos you need to know. All our crypto related question and concern can be found on internet or if you don't like the idea of just reading and want to learn it instead via stream videos then just hit Yt's search bar. Soon you don't need that channels and I know you will reached that point as your progress.
Just explore mate.
Also would like to thank you for sharing some youtube channels. I think Youtube is really great when it comes to reviewing and spreading info about the project.
