The correct way to do a pump and dump is to progressively buy small amounts of BTC at ever higher prices in a thin market.  That's one of the reasons MtGox often sees silly trades like 0.01BTC at $16.05, 0.01BTC at $16.07, 0.01BTC at $16.10, etc.  It's designed to run a thin market up.  As soon as you have enough followers and there's an increased amount of buy orders, dump a large amount of BTC in one hit.  The outstanding orders are filled before anyone has a chance to react.  MtGox users are relying on the bot programmers to be clever enough to program in all scenarios.  All it takes is one buggy bot with access to a lot of bitcoins to seriously affect the market.

It helps when there's a temporary sense of euphoria in the market too, as seen in the run up to $30/BTC.

because if you buy them all up and then sell them again you're paying up and down the same scale (or possibly a worse or better scale) so its not really manipulating the market at all... If you buy 10k BTC and then try and sell it high, you'll only sell it high if someone is suddenly willing to buy 10k that high.

If you buy 10K worth, you'll suddenly buy up every coin between you and some new price.  Most of the market will just watch the spread expand and think "....wtf?"

You'll get some sheep chasing you, but you probably won't start a buying frenzy unless you time it with some real or fabricated "news" that suddenly makes everyone want to buy at any price.

And if you don't do that, you've suddenly got 10K worth of coin that the market's not willing to pay more than 7K for.

With pump and dump you need momentum buying to make this work. Not just one large buy order.

Excuse me if this question is naive, but with such a small market what prevents someone from buying 10k worth of bitcoin, letting that be a view-able trade causing the price to increase, then dumping it when the market goes up a bit? Rinse and repeat you are manipulating the market with a large amount of cash and making a ton of money.

What other market manipulation tactics are we susceptible to with such a small market? What kind of voluntary oversight can we enact to discourage these tactics?


What's to say that the market will go up after you buy a large order?

I don't want to go into too much detail, but they're adults and very smart.

My apologies then. That explains everything.

I'm just mining to buy Lindens for a pet Pikachu in Second Life)

Remember that bitcoin crash a few weeks ago; one of my buddies was part responsible for that.  We did it with those Linden dollars from that game a while back."

Now here's the bigger kicker.  The guy who I was talking to is exceedingly smart, like genius level smart, and I believe him 100%

This same story is repeated on various forums, in various scenarios and situations, it's always 100% bullshit.

Always some spotty teen claiming "he" caused a market crash, hacked the servers or created a tornado. His lapdog friend running to forums like a faithful little brother & repeating everything he said with enthusiastic vapidness.

The crash was caused by one Mt. Gox account being compromised, and not your friend dumping a bunch of Linden dollars from Second Life.
That account was used to fill all open buy orders which means some were sold even at a token 0.01BTC price. He then attempted to cash out a ton of BTC but the $1,000 limitation kicked in.

My friend and his friends are all -- well I don't want to go into too much detail, but they're adults and very smart.  And like I said, I am 100% sure that if this guy says it's true, then it's true.

Also, I'm talking about the dip of going from $30 to $12 a few weeks ago, not this recent mtgox debacle.

Oh, well then, now I have good reason to believe you.

It went to $32 on speculation, it fell back to a more reasonable price on fear.

I'm wondering why is 32$ not reasonable and 17$ is.

To me, either bitcoin will be a failure in the coming years and 17$ is still completely unreasonable, either bitcoin will become really popular and anything below 1000$ is nothing at all.

Lets say you have 10 bitcoins and the market is VERY shallow.  You cause a panic by selling 5 of them.  

1 for 9
1 for 8
1 for 7
1 for 6
1 for 5

filling up a bunch of people's buy orders.  You now have 9+8+7+6+5=35 USD and the market is sitting at 5.  You now have funds to purchase 7 bitcoins back at the current market price 35/5=7.  You have gained 2 BTC for doing nothing.

This is a GROSS simplification, but you get the idea.

But you are asuming that there will be people willing to sell at 5. If those people were there before the price would have gone down already. Lets actualize your example:

You have 10 bitcoins. You sell 5 of them:

1 for 9
1 for 8
1 for 7
1 for 6
1 for 5

Filling up a bunch of people's buy orders. You now have 35USD and the market is sitting at 5, meaning that the last transaction was at 5. Now you start to buy and someone due to the "panic" is willing to sell at 7, the rest only at 9. So you buy 1 bitcoin at 7, leaving you with 28USD then you buy at 9. With 28 USD you can only buy 3 bitcoins and are left 1 USD.

So you started with 10 bitcoins, and end up with 9 bitcoins and 1 USD. You lost.

As I said the only way to win in this situation is to create a panic, play with the psicology of the people and make them sell. But this is risky because if people dont buy the panic you are the one losing money.

muyoso, I would add to your scenario a few scary posts on this forum about how BTC price will crash, etc.
also, maybe a few friends can trade in the same manner, and post in the same manner  Grin

killer2021 you are correct. "fear discount" is a neat term Smiley and very true.
small emotional markets (like bitcoin) are very easy to manipulate.
big markets (like FOREX)... not so easy. Soros made a billion in a day betting it's not practically possible, not even when the Bank of England was the manipulator  Grin

It went to $32 on speculation, it fell back to a more reasonable price on fear.

The difference between this and say, the US form of "capitalism" (more appropriately called corporatism) is that when people are greedy and speculative the regulators look the other way, but when people are fearful, banks get bailed out. There is nothing to bail out Bitcoin when people get fearful, so it falls appropriately and stabilizes accordingly.

This is a good thing. What's happening to government-printed fiat currencies is not.

1. Bitcoin is not a fiat currency.

2. The only way you can profit from doing what you propose is by playing with psicological factors, like creating panic and make that other people sell along you, so you dont have to masively sell. This is why we had so many trolls trying to create panic here in the forums. But this is a very dangerous game because you never know how the people is going to react, the psicology is always different, so you can end up loosing big time. Its quite risky.

The only conceivable way to profit by selling a lot is if you didn't have to sell much and you also held a short position on a stock. If somehow by you selling a bunch, panic ensued in the small unprovoked lowering in price and in-turn caused the price to go down even further, you could profit considerably. This are, however, no short positions available on BTC.

Thinly traded markets are easily manipulated.

Above all else, BTC supporters need to remember the above.  The game of pumping and dumping thin markets is as old as the stock market itself.  The same tricks have been employed countless times to lure the suckers in and then dump stock before anyone else can.  The run up to $30 was a classic example.  No logical market behaves that way regardless of wishful thinking about difficulty driving BTC's price to the moon.

This is a well documented phenomena in markets. Well studied by economists. Fear and greed is the trick. What happens if you cause panic. How do you cause panic? Sell a shitload of btc, like a lot. Once people see the price drop 10$ in an hour they will panic and sell. All of this artificially induced selling is what I call the fear discount. On the other side if you want to create an artificial boom simply buy up lots of btc very quickly. The price will rise very fast and when people see this they will think, "holy crap, I better buy now before I miss this rally." Well, once you've finished buying then the price will continue to rise because of people buying into the rally. This increase in price is what i call the greed premium.

If you look at any market, its all greed and fear.

The best time to buy is when here is fear in the market (ie. the sky is falling!!!!!) and the best time to sell is when there is greed in the market.

The solution to this problem is speculators, the more speculators with even amounts of buying or selling power will make it more difficult to cause one speculator to rise or drop the market. Speculators are good for the market! They aren't bad!
