the #1 problem with bitcoin is basically nobody spends it.
BTC is decerntralized cryptocurrency. But 1% of the population holds 99% of the money. It is not fair for 99% of population who have to pay the equivalent amount of fiat for BTC at the exchange. It is the 1% of population who is a member of the co-founder or grab extensive mining rigs. They will scoop great profit from the holding of BTC unfairly.
You can hardly argue that it is unfair considering most of the early adopters shaped much of what we have today and without them we wouldn't have Bitcoin in the first place. As a result of their contribution the have been rewarded by having earned a large amount of wealth from this. It's like saying that it's unfair for Bill Gates to be so rich as he was one of the few to make personal computing accessible. He simply has earned his just desserts for contributing what society believes to be a very valuable contribution.
Over time the early adopters will sell their coins to newcomers for a profit. The higher the price of bitcoin goes the more of an incentive the early adopters will have to do this.
