Now, I am sure that 10 years may not be enough to silence critics -- big, small, known, unknown, influential and not -- of bitcoin as there are still those who are wishing (or rather predicting maybe) that bitcoin can be zero...soon! An example of old-school critic is Warren Buffet who is a popular and very successful investor but not inclined to believe in the value and future of bitcoin.
Then we have many media influencers and an example of this is another old-school named John Crudele and he is writing a column for NYPost.com. His objection to bitcoin is immortalized in his own words: "Bitcoin will soon be worth zero. But until then criminals will still be able to use it and other digital currency to move money around the world without being caught."
At the end of the day, we live in a democratic space and we welcome diversity of ideas, opinions and convictions so we still appreciate people who are in the opposite side of the picture.
