Gentlemen, do not forget that there is a guy who bought 400k USD worth of bitcoin causing 4USD slippage, watching price go down

That buy can come from the same who dump millions today.. so means nothing.
i just saw how a 1000 btc buy wall got eaten in less than 10 seconds in the morning

Let's assume he indeed has those 35k coins. I can see the FT title :
"Bitcoin Billionaires"
The Winklevoss Brothers , .... and a pacient in a mental institution in Finland.
The best part, I bought 120 BTC mostly on that lunatics advice

well, prepare to lose money soon, there are cleary signs that the dumpers are already online on gox, you bought 120 btc around 100 when you could bought them lower.
but.. when miners dump too many btcs they attract the noobs panic sells.

big walls on both bid and ask sides...
this will be quite insteresting
