the reason for bitstamp price is :
bitfinex which one can use as an arbitrage tool between gox and bitstamp.. stopped offering gox bids.. due to the latest news around gox (dwolla).
it was an easy profit: buy on bitstamp(trough bitfinex).. sell on gox. hence price was always in synch with gox on bitstamp.
bitfinex is working on a solution: api to allow bots and marketmakers, it will be up (well i guess somewhere in the comming week(s))
once we got volume on bifinex.. bistamp will follow gox price again (like it did when bitfinex a few weeks ago started their integration with bitstamp)
Also the move of bitfinex to not use gox anymore is probably temporary until gox get's its shit together(but with goverments this can take a while so this is more of a long term view)
so what i'm doing now: sepa new fiat over to bitstamp and buying cheap coins.. (i'm not rich so it will be just what i can afford to lose and will not move price much )
because i know the price will go up as soon as the api thing is working on bitfinex Or when gox orders are allowed again on bitfinex.
now if many people buy new cheap coins on bitstamp with new fiat. it will sync with gox soon enough.
now for the big ask side;. it will go away once gox price goes up.. the bids will follow also there enough buy power at bitfinex to eat those 4k walls at bitstamp
once price at gox is high enough
and there are enough bid offers.. on bitfinex and bitstamp (which might be when api + bots are up)
so basicaly.. if you have some fiat left to play with.. buy cheap coins at bistamp.
