I have noticed an interesting fact->
I've sold from 471 to 450 and then posted a buy order and 441 and I made a nice profit. But I really don't understand why people panic and they sold immediately.
Also, the're is no buy support, NONE, to 188 there is only 5 btc.
THe sell support from 48--550 is more than double, 11 BTC
It's what the sheep do, I've seen silly little sell walls drive the price down and down on some coins lol, they just look at the lowest price and sell below it.
