The title of this thread is "Someone is trying to intentionally tank Bitcoin price".
That assertion is absolutely correct, and it has been happening for weeks. Massive DDoS attacks on most pools, most exchanges, and now an ongoing "Transaction Malleability" attack. It is clear that someone from the other side is not happy about the existence of Bitcoin.
This is not just the "nature of the Bitcoin market" as Holliday puts it.
This is not just the "nature of stock/commodity/currency speculation" as Bitcoin_is_here_to_stay puts it.
This is an attack, a multimillion dollar attack, lots of hardware, lots of skilled people, lots of hate.
Now the question is "what are we going to do about it?".
"Now the question is 'what are we going to do about it?'."
There aren't really any get rich systems in life that work for everyone. If there were, then EVERYONE would be rich, and rich would not be rich; it would be average.
Bitcoin is not for getting rich, although there are a few that will. Bitcoin is for using as a medium of trade, the thing that money was supposed to be used for, until we found out that the bankers had turned it into a get-rich Ponzi.
The things we can do about it are:
Spread the message about how Bitcoin is better than money;
Use Bitcoin rather than hoard it;
Continue to develop innovations that use the Bitcoin pattern.
We are the people who can do this, The fact that we are in this forum and posting or commenting shows that we are.
