Bitcoin has seen a huge momentum and rise this year and today we discuss wether it is in a bubble. I wanted to make this video because I received an interesting question from one of the viewers. We discuss both Bitcoin but also Ethereum and the cryptocurrencies based on Etehreum and the Ethereum ICOs.

What do you guys think about the points listed in this video? Do we have a Bitcoin Bubble, Ethereum Bubble or cryptocurrency bubble in general? Are you afraid of a Bitcoin crash?
