Coins needed for 145 went down from 11k-ish to 9.3k now, the support doesn't look that strong but selling pressure doesn't look strong yet either. That could change pretty fast though.

How do you know the crash was caused by someone dumping 69k coins at market? Is this a verifiable fact or speculation on your part?

If speculation, why do you believe someone did this?

I don't understand who in their right mind would do such thing?

I mean it's a very poor way to sell a position so large, right? Since you will get serious slippage?

Of course there is a verifiable fact. Just check the "trade history" on bitcoincharts or similar, or follow the "time & sales" on http://bitcoin.clarkmoody.com/. I was trading when that happened, in fact I was very happy because of the unbelievable buying opportunity until Gox fucked up and halted trading to induce "market cooldown". You can check the forums and you will see I was the first one to post about this "market cooldown"

I had to wake up at 4AM to be ready when Gox reopened, just to see how my big buy order at 35€ was not fulfilled for just a couple of euros (bottom in € was 37€). That really pissed me off, I think I should trade in USD, as it's much easier to spot support and resistance points.

Doubtful, if you have followed this market for long, you will know that at certain price points the buying/selling volume will spike up, probably bots triggered by price movement, the same thing may happened during the crash.

Thanks, I believe you. Wauw, that does explain the crash.

Is it possible that this kind of selling does give the best price?

For example, did he get that order filled?

If yes, he probably got the highest price anyone got considering the amount of coins he had to sell?

As a funny note, there was a few users who spread the rumor that the one dumping the 69K that triggered the crash was Silk Road (for example, see: https://bt.irlbtc.com/view/85687.msg1804571#msg1804571)

The dump was real, the one who did it's unknown (at least I have seen no proof other than rumors and different posts).

And of course a dump triggered the crash - it always start like that. The BTC is so ridiculously illiquid that a tiny dump of +10.000BTC would trigger a panic selling and a huge crash. Heck, a 200KBTC dump would take us to low single digits! That gives you the idea of how easy would be for a BTC enemy with not-so-deep pockets to destabilize BTC.

And now imagine that an old miner decides to dump +500KBTC coins because it's time to be rich, and he doesn't give a fuck

On what day? Because that is the chart for the April 10/11 crash.

Wasn't that exactly what I said?

Big price moves don't happen unless big dumps or buys do.

Not much happening. Care for a recap of recent events in non-vertigo-inducing log scale?
