I think explaining Cardano in a way that it builds on the concept of Ethereum is somewhat misleading. While it can be stated that Ethereum is THE second generation cryptocurrency and Cardano is a third generation cryptocurrency, the philosophies are vastly different. None the less, it is a great pick especially at this time to pick up some ADA in my opinion (not a financial adviser), as the long term vision is clear and achievable with this great team. I encourage anyone to look more into the Cardano project and not just blindly pick up some coins.
