No, no and no. If you read that link that you have put you will see that "Wallets with the most bitcoins belong to exchanges". Then I don't have a problem with few people owning a lot of Bitcoin, like early adopters, or Satoshi, or people who invest a lot of money nowadays.
Lately I'm hearing the same complaint from people who until recently were saying that Bitcoin is a scam and that it's going to go to 0 and that it's going to be banned....
Well, from those same people I hear lately that it is unfair that Bitcoin is badly distributed.
Moral of the story: buy Bitcoin and shut up your mouth.
We all know that Bitcoin is not a scam, but I was impressed to see that the concentration is only in 1% of the wallets, it is too much of a difference, but hey, this happens in everything.
