Thanks for the video !
On a side note, I assuming you are trying to build your name via the video, my advice is to try practicing with more inspiring voice because the voice is very important.
Yes the voice and the video quality are the most important in a good youtube channel if the video quality isn't good then the people who visit your video would go onto another just because your video isn't of such good quality as others and also the most important thing is your content always keep your content good enough and of some quality for others, if no quality or nothing to gain then they will never visit your channel again.
Video is one way to provide good advice and knowledge, it's because the video has a unique way and can make us much better understand and provide knowledge something much more clearly.
The more interesting the content is made the better. Especially when giving information about how to choose the best ICO and I am sure for anyone who wants to learn the world of crypto then the video is one of the better options in understanding far better that will benefit our future.
