why green is bigger and bigger, but price keeps going lower and lower?
Bitcoin can be moved onto and off of an exchange in minutes. Fiat takes days.
Smart people try to leave coins off exchange and move them on only to trade and get them safely into cold storage as soon as possible.
Because fiat takes so long to move, it becomes necessary to leave it on exchange longer, so people leave it in the form of bids, often staggered but sometimes as distinct walls.
