its going to 580-600 now for sure.
nothing can stop that one dumper on stamp.
One dumper? These are 100's of idiots in total panic who are selling. What exchange are you looking at?
looking at stamp. obviously one entitiy who sells below market price ( all other exchanges ) for days/ last week.
normal rational trader wont sell below market price.
there is still no valid explanation why theree is such a gap.
I think one reason Stamp is a very important exchange is not the volume they do, but probably because the exchange is easier to change btc to Fiat. Other exchanges may have similar or higher pricing depending on the supply and demand, but like Mt Gox awhile back who consistently was 20-30% higher than other exchanges in their case because of problems putting money in and taking it out.
