If someone bought 20BTC worth of coins, would you be willing to buy higher knowing they could dump on you at any moment?
Buying 20 BTC, is exactly the same thing as putting up a sell order of 20BTC, or selling 20 BTC.
That's the only reason it went down.

Right now.. there are quite a few sell orders of 2-4BTC over 300, maybe 20+ BTC total worth in ITC.

Guarantee you, most whales aren't gonna be stupid enough to come in here with this order book.

If you guys really want it to go back up? take your sell orders down
And give whales a reason to pump; maybe put some 1-2 BTC sell orders around 200-250 as an incentive for them to flip it and knock the price up.
You can buy back later and help it go up ; that's also one of the biggest problems right now, its that people are holding bags very high instead of just selling and buying back in and giving us some of the volume we need in order to go back up.
When it gets high enough...you can put your sell orders back up..or if you're smart just sell when there's enough liquid.
