Regarding the downward price pressure on stamp. It seems that sooner or later this whale or group of whales is going to have to run out of coins. It seems that there just are not enough others following suit in order to make the ongoing selling to cause any additional BTC price downfalls. Having a lot of difficulties getting others to follow and getting the price to go below $351.20. S/he / it does not seem to be giving up, yet, but at some point (hopefully soon) is going to run out of coins.
But how much of his coins is actually selling to other hands, as opposed to selling them to himself?
Massive support Walls go up...everyone pauses...illusion of support, whale devours his own Wall, anxious holders of BTC looking to sell, sell off in droves....
....then when down move is out of fuel, same trick applies on the way up, but in reverse.
That last Kilobomb that Stamp whale dropped at $350 support (again, he is still probably holding most of the 850 BTC that he sold), seemed to be taken with indifference by all other exchanges, so up pensively we climb?
