Cardano is currently sitting at the top 10 of coin market cap. It came out of nowhere and stayed there. 

Why is Cardano valued so high? What are the innovations that they bring to blockchains?

I cover all that in this video and answer the question is Cardano overvalued.

I have previously done a quick glimpse review of Cardano right when they came out. This time I dove deeper and overall my understanding of blockchains have improved, but I come to very similar conclusions as before.
