2. Bigger fish sells 100k BTC and brings us down to $6, and we rebound to $8.
3. FAIL
no, no.
No fail at all here. The Ask wall is still there and all the smaller ask orders used for such a money making scheme are also still there. All the manipulator has to do is to wait for the market to come back to reap the revenue. And while doing so, the manipulator might even construct another "system" of paired orders in between to make even more money. All he needs is liquidity. And someone who can move walls of the size we saw the last days does have lots of liquidity.
Yuhfhrh is right. It only works if the market stays above the bid wall. Otherwise, you will lose money.
"All the manipulator has to do is to wait for the market to come back" -- You assume that it will come back, and you will lose money if you are wrong. Let's say you set up your walls when the value hit $15 3 months ago. You would be out a lot of money right now.
"All he needs is liquidity" -- you mean all he needs is an infinite amount of money.
I think we just saw an example of how the system could fail. Mr M just bought himself 8000 btc
I would consider owning 8k BTC a win no matter what the short term may bring.
Me too Working on it...
