The bigger issue here is that if a small percentage of individuals own a large percentage of the total bitcoin they can easily manipulate the market price by buying and selling large quantities in a co-ordinated way.

This will often be coupled with FMO such as that coming out of China recently to cause a crash in price. These "Whales" then buy up bitcoin for those panic selling, and wait for the price to go back up.

This is why we HODL people.

Infographics like this illustrate the whales power of the market, don't get played and sell your bitcoin when you see a crash.
