What we know for a fact is, there will ever be 21 million coins, and there are increasingly less as they get lost, total supply is almost mined.
21 BTC holders shall find glory.
Coins are distributed well, even with no source of that to considered as a proof, we really have an increasing number of bitcoin users throughout the globe. No way only the whales are the one who are making such buys that's why we are currently sitting at the current price today.
In case a hacked will happen today, I don't see the price to experienced the same scenario happend when Mt Gox showed their true colors. Back then most of the coins are being traded in that exchange unlike today that coins are playing along with several big exchanges. So a hacked of single exchange today will not be enough to make the bitcoin price decrease continously.
