I agree on author's Cardano remark. Overvalued.
Even if we say that they will disrupt the markets no other company has received so high valuation (17bln USD!!!) being so far from the FINAL working product. It will take years to develop and implement it. Lets take Uber for comparison which is a recent great example of disruption, they raised less than 0.5bln USD in the first four years of operation from venture capital actually having a working product. Cardano can't disrupt the market in the coming year. It will take years to become a true disruptor if they succeed. Their valuation will definitely go down in short term.
