First, I appreciate your effort to make this video and upload it to your YouTube channel. It is easy to understand.
Can I give you some suggestions? Although I am also not good enough in creating this kind of video. But after watching it, I think about these:
1. The video is too short, it is only 1 minute. I know that it probably doesn't need many times and it depends on the material of the presentation, however, I think that it will be better if you can create a video around at least 5 minutes.
2. The topic is too common. If you create this kind of video, people will not be interested too much in your video because there are many similar videos related to this very basic information about BTC, in which, they are probably more completed and clear explanation.
3. It is better to make a video that is specifically about how to utilize the BTC, for example, trading, investing, and more. However, if you do not have any ideas about it, you can also create a video about Bitcoin in a more specific explanation. Not only that basic thing. It will take a long time also and it is good for your video.
4. The way you set the timing to display the sentences is a little bit too fast, You should consider the way or the time for people to be able to read your explanation and understand it. So, you may give seconds to let viewers read the sentences, make some seconds of pause before continuing to the next slide.
5. It will be more interesting and clearer to add voices, not only music as the background. but note, if you are adding voices, ensure that the music background should be lower.
6. Please pay attention to grammatical writing, there are still some errors. I know that I am also not good enough in English grammar because it is not my first language. But, once you create a video and upload it on YouTube, it will be better to check the grammar at first before uploading it. It will be better, mate. You can use Grammarly for help.

Here are my suggestions, hopefully, it will be helpful. Be spirit to continue your good work.
