Bitcoin according to Satoshi Nakamoto is supposed to be the new currency, relying heavily on the idea that the world will soon use this currency to make transactions..

How will these transactions be made if there is only a finite amount of bitcoin available and they are so poorly distributed? Some people have hundreds of bitcoin while others have one, two, or even parts of a bitcoin...

And to make it even more interesting, people are investing and holding onto bitcoin. So, how will the world be able to use bitcoin in the future  if only the miners and first investors own majority of the bitcoin?
