What?
Are you telling me if Satoshi comes and dumps off exchange 1 million bitcoins would be bullish for the price because lot of people would be buying?
When you sell something in the other side there is a buyer... that's granted. But what matters is sellers to buyers ratio. If you have more sellers price go down...
That's pretty simple, dude...
That would be like the equivalent of the end of Mt Gox. It would remove the Sword of Damocles and confidence would boom. That one million bitcoins would be eaten like chow in a mess hall.
But we are speaking about short term price. That would drive the price instantly to something ridiculously low for a long time.
How can be that a bullish scenario in the short term?
Quite the opposite. It's the worry about the bitcoins that are not being sold (hence the low volume) that is keeping price down. Sure the price will go way down, because exchanges still use the Mt Gox model. If bitcoins were only sold through brokers and ATMs, the market would not be nearly so volatile.
