k so here's what i'm thinking
these bids walls are for real.. someone i making a statement "i want to buy XXXXX coins at 4.6"
the market will respond in 1 of two ways
1) fill the order
2) make a counter offer
since 4.6 is a really low price i think #2 is more likely
we'll see a nice big fat ask wall form around 4.8
at which point we will be in stand by of take off mode, just like 2 weeks ago when we went from 4.8 to 5.4
edit:
secret option #3
order will not be filled
counter offer will not appear
which means up up up
looks like we are going for secret option #3 , oh joy!
