I have "discovered" a serious flaw in NXT. The IMF exists to stop the opposite attack on fiats, eg. massive short selling. CfB says this attack is well known, but I didn't know about it and so maybe you don't know about it either. I was told to post it publicly, so here it is:

I have come up with non-standard attack, call it financial attack.
Short term, this "attack" would be considered as fantastic by most NXT'ers and it consists of simply buying up all the NXT. Crazy, expensive?
Consider you are large govt with fiat of trillions of dollars, billion dollars is lunch money. They can easily win the "war on NXT". What happens if large scale accumulation of NXT occurs with $10 billion budget. How much of NXT will be left?
All accumulated NXT can be destroyed by sending to genesis acct permanently crippling NXT market. Or it can be converted to many darkNXT accts so nobody would even realize it is happening. I am assuming if we started seeing a lot of NXT being sent to genesis acct, we would notice, but so far no darkNXT detection is implemented. Without realizing, 90%+ of NXT could be destroyed with $10 billion.
Actually at $10 NXT, who wouldn't sell their NXT, so how much NXT will survive a financial attackers $10/NXT bid, especially if it was done cleverly to avoid detection? 1% left? Maybe even less. With .01 precision, smallest increment will be 10 cents even without any more price increase. NXT would be useless for microtransactions, until support is added for microNXT.

P.S. Solution is to not destroy NXT when sent to genesis acct, just have it automatically put into community fund. Also, PREVENT darkNXT at the protocol level. I guess evil financial attacker could simply destroy their key though so even with darkNXT fixed, there is no solution to this attack.
In this case it doesn't matter if the NXT send to genesis account are destroyed or not.
Because the effect would be the same if the NXT stay in the big buyers account without the intention to sell them. They would be out of the system.
And this "attack" work on all cryptocurrency.
And I think if a single buyer can buy all of the supply of a currency, then this currency is probably not threatening enough for them to bother
