There are a ton of that style explainer videos out there, and many marketers think they aren't professional or effective. I disagree.
If it conveys the concepts that's great. If it has an emotional hook even better. In fact that's the key to a good ad piece, it snags the heart. IMO this video isn't the greatest at that, but it's on the right track.
For entrepreneurs or those who have some knowledge of marketing techniques I believe this video has an excellent chance of reaching them. Not so much big business marketing, but rather those with a good youtube, facebook or blog following. In short the savvy individual who wants to extend their reach using Bit Teaser blockchain tools.
