Guys you know that panic selling caused the massive windfall right? You are literally talking metagame about panic selling...

AKA: Lag/DDOS no longer to blame.

(can I post here already? not sure. guess I'll find out in a second.)

Here's what I posted a few moments ago on a related thread on reddit:

Assuming spamming of micro transactions was in fact the reason for the crash (that, and of course herd animal behavior of panicked traders), shouldn't this be easily solvable?

One solution would be to demand a small fixed fee for each transaction, making it more costly for spammers to perform such an attack.

Or alternatively, and perhaps a bit more elegant would be implementing an algorithm that evaluates, based on a traders current behavior, this trader's "spam potential". Based on a few simple heuristics (number of orders per hour of that trader, average size of orders) the algorithm assigns each trader some numerical value that expresses how much like a "spammer" the trader behaves. Then, if the trading system starts suffering from lags, each trader whose "spam potential" number has reached a certain threshold will see his ability to buy/sell throttled (but the effect wears off over time).

Wouldn't that stop the problem immediately, at almost no cost (there would be the occasional false positive with the spam filter, but that's a small price to pay I think). Why doesn't mtgox implement such a trivial solution? What do they have to gain from having their trading book flooded with useless spam? And I also simply don't see what they possibly could gain from allowing such an easy way to manipulate the market.

If you watch the 0.02s, and there are many of them, they are coming from HFTs (High Frequency Traders) pushing the price up, up, up and they sell sell sell, using the 0.02s to drive the price to lows and then buy, buy, buy.
Watch the activity with the 0.02 orders. You can see it happening.

I suppose the exchanges could limit the number of trades allowed per second/minute. But the HFTs might go elsewhere... causing the problem on other exchanges. Does MtGox lose money if that happens, or would it restore confidence to its users.

Or should we look into becoming HFTs ourselves and ignore the bright future bitcoin could have as a currency and trash it like a used toy for some greedy profit taking today.

Just wondering.

Confirmed no DDOS: https://bitcointalk.org/index.php?topic=172991.msg1801862;topicseen#msg1801862

^^ they have NOT been ddos attacked...and the rate lost 100USD !


Mtgox is offline btw

Oh please not that again. Mtgox have confirmed they was no DDOS. They just can't scale their operations. They aren't sorry either. https://mtgox.com/press_release_20130411.html
Repeat after me: there was no ddos, and no conspiracy to crash btc. People panic sold, that's all.

If all this was caused by only their trading system lag, then why did other exchanges all go offline at the same time as well as the forum here being overloaded. Either the entire Bitcoin ecosystem is built using Intel 286s, or there's a little more to this than than meets the eye.

Wut, you always leave big some breaking orders way below current going rate.. Those orders were already there.

I believe, like every other currency on Forex, some amount of manipulation of prices is possible. To what extent, depends on the size of the Player. Most of us might be too small , to drive the market individually but a really large player could easily drive prices up buying if his purse runs in in 10 of millions. I`m pretty sure a lot of investment guys might have hopped on to BTC to make a quick buck.

What I'm trying to point out isn't the exact price point of each buy order, rather the fact that such large orders were made ahead of the crash.  We're talking about someone (or multiple someone's) with MILLIONS of dollars in ridiculously low buy orders.  If someone seriously had that kind of cash sitting in a mtgox account, don't you think they would have already bought to ride the crazy wave that was currently occurring?

I'm not saying it's proof... but it definitely points to forewarning.  If mtgox is now claiming that a DDOS did not occur, then one would have to speculate that that insider manipulation could have been in play.  I mean, how hard would it be for an IT guy or someone with access to mtgox hardware to make a small tweak to negatively effect trading?

All I'm really saying is pay attention to those home run ridiculously low buy orders... when they start popping up, you may want to get ready for a quick sell.

I try to imagine this number. 75k accounts in 1 1/2 months and the following consequences.
The rise of created accounts is nearly the same as the exponential price gain of bitcoin in the last weeks.
(despite the drop today)

I'm really stunned by the way this whole experiment is gathering (i still see it as that, because imo the "real" big players are still not in the game and that time will come sooner than later)

I can't wait for the future of bitcoin and what (senseless?) attempts the governments and financial regulators will start to put it behind bars.
The comparison is perhaps kind of naive (i'm just a cgi artist, programming is not really my strength)
but if they really try to ban bitcoin with laws, is it possible to handle the bitcoin system in the same way the piratebay is secured?

Because the only other possibilities would point straight towards a kind of "regulated" (as said if that is even possible) sideway currency integrated into the existing market or bitcoins could only be traded via tax havens (which is perhaps kind of logical because in europe there's a beginning chase for tax refugees and these countries already are the shelter for most betting companies for example).

Perhaps i miss the point or I'm wildly speculating right now after my third cup of tea and 4th cigarette 
but it could be that with the ongoing obsolescence of fiat money, tax refugees really start turning to bitcoins in the future (only as the price rises. right now bitcoins are not the best possibility to transfer such large amounts of money). For tax havens it's much more easier to get some servers running and trading bitcoins instead of doing the old phantom company style and trying to blur the money flow.

...it's kind of sad in a way but bitcoin could become more and more attractive for tax refugees in combination as a eventually side playground beneath existing stock exchange for exactly those speculating assholes who were the reason in the beginning that bitcoin emerged...
(otherwise these pricks could have greater interests in bitcoin as a nonspeculative currency because it's not fluctuating. Perhaps that evolves to a possibility for the little man to finally outwit them and profit on their destructive behaviour towards the society)

oh bitcoin where will your future lay....

it's funny that every bigger step of humanity has always these two faces of a coin in its ecosystem.

but compared to the developement of the internet as it is today in times of partially senseless overregulation in fear of probably pushing the next possible revolutions at a certain point like during the Arab spring, I'm confident that somehow the whole idea will find its way over the centuries.
(It always has! And perhaps no matter what kind of money is put into bitcoin in the future, the more the better.
It's goldrushtime and I hope that hype can regulate itself over the years with a following prosperity for everyone)

uh kind of went off- topic on this one  , sorry for that and eventual grammatical disasters, don't bash me, I'm just a fascinated overslept excited newbie starting to get into the think tank (perhaps some operator put my post in a "mysterious future monologue"-thread)

.....where were we

ah...

back to mt. gox

Probably just people preparing for the worst. Also, exact multiples of 10 is a logical price point, so it's natural that many people's bids will congregate at all the 10's and 20's.

If I were to think up a quick-and-easy price point to use as a "just in case" bid order, I'd just go with something like $120. So would a lot of other people. Only a crazy person would go with something random like $127.28315 

Mt.Gox's post still doesn't explain the large buys. Good observation OP

Some very intuitive and forward thinking going on here, love it.

Thanks for pointing this out, it might have slipped past me otherwise.  When I first read that I thought they said they were going to be closing for 12 to 24 hours lol.  Then again with how well the service was functioning the past day, they may as well have been closed that long.

sorry for copy and paste from the senior forums, but just wanted to throw in this statement with impressing numbers from mt. gox facebook page (35 min ago):
https://www.facebook.com/MtGox

I'm curious about the coming months with 75k traders throwing their money on the market, in combination with the big impact on the media and the current situation in europe.
(Slowenia seems to be the next shaky candidate and cyprus perhaps have to sell their gold reserves)  
looks like the rough times have just begun.

That's an interesting observation, dhenson.  I definitely had the feeling that the crash today was orchestrated and manipulated, and since it appears to have been successful, once can only expect that there will be more of them.

What I would prefer to see happen is to have the tier 1 internet providers push down rules to requiring the adoption of source IP address verification and disabling of recursive DNS from non-trusted addresses to solve the largest DDoS attacks from happening.  It's long been known how to stop DDoS amplication attacks from happening, so it would be helpful to have the loopholes closed down through the hierarchy of service providers - especially in the US where the most open recursive DNS servers are located.  Markets will always be manipulated, and bots are allowed on stock and fiat currency exchanges so it would be odd - and particularly ironic given the roots of Bitcoins - to disallow their (ie. "pull the plug") on their use in bitcoin exchanges.

Also, it would be really helpful for Bitcoins on the whole that there would be more competition in the exchanges. Or we need our one major exchange to do a better job. I read in the MtGox blog that people don't understand how hard what they are doing is... and that's probably true, but they need to step up their game, and if that costs too much then they need to raise fees to raise money to step up their game. A queue of 19000 people for verification and trade latencies of over an hour isn't going to cut it. So much hinges on MtGox either being a highly effective exchange, or else MtGox having lots of competition. If we keep on course where there is one major exchange that is overwhelmed, then the momentum that BTC has as an alternative international currency will decrease.

We also need exchanges that can reduce volatility by allowing short-selling - people who short currencies (or stocks) have a bad reputation, but they do help substantially with volatility by creating sales during run-ups. Pretty much everyone who has been around currencies (and commodities and stocks) for a while can spot a bubble, and people shorting (or borrowing a currency in order to sell it) counter-act price increases with increasing price sales. Short selling doesn't solve the problem of bubbles, but it definitely helps with decreasing volatility. Until there are some tools for allowing shorting, we will continue to see dramatic BTC <-> fiat currency volatility
