However, these experts also fail to weight in the positive impact of bitcoin in the society if ever it becomes mainstream. All eyes are focused on the negatives while completely ignoring the positives. Mining does not threaten our very existence, petty trash talks from different political leaders do. Over-harvesting of natural resources does more harm than bitcoin mining. Economist or even experts I don't really care what they have to say when it comes to bitcoin's value. No one can predict its movement in the market and those FUD will always come if the market is bearish. We have lots of emotional investors coming in everyday hoping that their investments in bitcoin will make them rich.
