This is just one of the many negative publications on bitcoin, such does not deserve our attention to be honest with you, for bitcoin over the years has proven each and every one of this companies making negative publications and comments against it wrong as we all can see, there is absolutely no need discussion things like this anymore, for even if they were competing against bitcoin with their gold, bitcoin has clearly won, and the loss is theirs because today, bitcoin and gold are both existing and co-habiting, it's their loss because they would have invested in both assets and make profit from both.
But all the same, it's what it is, like I would always say, it is impossible for each and every one of us to believe in bitcoin at the same time, even if we all hear and or read information about it the same time, it is impossible for us all to believe in it at the same time as result of our differences in psychology and mindset, humans think and treat matters differently, so, I am not surprised and won't be if even today, some people still refer to bitcoin as a scam.
