As for an example why I put the dolt Rassah on ignore (another confirmation that IQ tests are indeed often wrong)
Hmm, I wonder how AnonyMint knows that i did something to confirm such a thing, if he has me on ignore?
the entire point of inciting the weak hands to sell, is that it only risks a small amount of your holdings in order to incite a larger flow of sales from weak hands. So even if there are others waiting to buy, you are also waiting to buy.
Sure, but to incite you first have to sell. And you'll need to sell/risk increasingly larger amounts to move the market as Bitcoin exchange volume grows. And there are a lot of strong hands waiting to buy who are waiting for such flash crashes, who may buy up quicker than you. Think it through: every time you sell and then buy again, a part of what you sell gets picked up by your competitors, and you don't have enough to buy everything you sold back. If continuously repeated in a competitive market, such action typically ends with you running out of money. You could argue that there are enough weaker hands to initiate a price momentum of continued selloffs once you start the sells, but, as has been pointed out by FenixRD, and with established Bitcoin precedent, each such crash only teaches people that these crashes aren't real, and makes people more resistant to such panics.
Presumably if you are that rich of an insider, you already own the exchange too. You created an exchange because it was insane not to.
What would prevent a competitor from buying coins from you on your own exchange. And if the answer is "the exchange owner trying to flash-crash the market," that action will be quickly found out and complained about loudly, likely causing the exchange to be accused of fraud and lose business. Sure, this rich insider will make a bit more money, but they will lose their echange business, and, since they would likely be publicly known (people tend to not trade through anonymous exchanges), they will become a real life parriah. Oh, also, a drop in the exchange they own not only creates a massive arbitrage opportunity with other exchages, one which trading bits will eat right up, but also makes other exchanges follow down, and allows competitors to buy up cheaper bitcoins on exchanged this wealthy insider doesn't even control.
Really, the only method for such a scheme is to create an exchange that is anonymous, does not allow API's and bit trading, and somehow still convinces enough people to join to make the trading volume actually affect the average global bitcoin price. Not likely.
