the major problem that I see with Bitcoin is that a large percentage of the available coins have already been 'mined' by early adopters. The creator of the Bitcoin protocol him/herself almost certainly hoarded a large percentage of available Bitcoins in the first year of its existence.

the major problem with the U.S dollar is that you were born in the late 20th century and you did not personally get rich during the gold era, now you see alot of rich people hoarding billions of dollars and you are stuck in a minimum wage job...
this is the same argument you see a child have, that his older brother learned to walk and talk before he did. im sorry that you didnt get there first, but for atleast 100 years you still have a chance to make your life successful, dont blame your elders for getting there first
