Good short video.
But in the end part, I think it's not appropriate that after telling the basics, you will end it at,
"What are you waiting for? Invest in Bitcoin".That was also caught my attention, probably they will think profit in a wrong expectation. Just remember that investing in Bitcoin is very high in risk, if they will not understand the full concept on how the right investment of Bitcoin, they might lose and didn't even see there porfit.
At the first glance I appreciate the video, the effort of making this I know it took your precious time. But it is pretty good if you include how Bitcoin works understand the volality thing. Also the usage of Blockchain technology behind on this Bitcoin.
