Doesn't Bitcoin unfairly benefit early adopters?
Early adopters in Bitcoin are taking a risk and resources invested in an unproven technology. By doing so, help Bitcoin become what is now and will be in the future (hopefully a decentralized digital currency ubiquitous). It is fair to reap the benefits of your investment success.

What if someone bought up all the existing Bitcoins?
Bitcoin markets are competitive - that is, the price of a bitcoin will increase or decrease depending on supply and demand in certain price levels. Only a fraction of bitcoins issued to date are in the exchange markets for sale. So although technically , a buyer with a large amount of money could buy all the bitcoins offered for sale , unless the holders of the remaining bitcoins offer them for sale too, even richer most determined buyer can not reach them.
In addition , the new currency is still issued daily and will continue for decades , but over time the rate at which output decreases to negligible levels. Those who are mining are not obliged to sell their bitcoins so not all bitcoins even reach markets .
This does not suggest , however , that markets are not vulnerable to price manipulation . No significant amount of money is needed to move the market price up or down , and so Bitcoin remains a volatile asset. Source
