I wouldn't call myself a bitcoin fanatic (I hold a very small amount, just for the fact of making myself learn about blockchain and cryptocurrencies), but these articles are not well-researched.
They don't understand the difference between Bitcoin and Dogecoin, let alone the difference between ICOs and Bitcoin, not to mention their misunderstanding that blockchains are a technology, not Bitcoin.
The article even admits Dogecoin's creator was always skeptical and made the coin as a joke, so him suddenly saying he is skeptical is just about the least shocking thing.
