If you check the order book of Bitfinex, every $50 mark there is a huge block. it starts with huge sell orders at a certain price, then relatively big ask orders flow in so sellers are bidding just above to fulfill their order quick. Sellers want the same so they put their orders above the sell block -> price rises.
At a certain point, the process reverts. buy-blocks are removed and price drops. This swing is going on for a few days now, and giving substantial profits for those who ride it.
I'm quite convinced something artificial is trading with itself pushing back-and-forth(just like a kid doing on a swing)...
The trend not following any of the indicators based on technical analysis (which most, at their turn, are based on psychology and crowd behavior) is like an inherent proof this is not human behavior.
I believe in the psychological barrier of 10k everybody wants BC to achieve, but imho it's impossible this finale can be pushed by real people with real money in only one go (and only two days!) without correction levels in between.
This looks like a giant pump/wash. The press is still writing this is a final proof of mainstream adoption, but I don't think so... It's a self-sustainable system and no influx of USD is needed to maintain this (Tether). Transfer back and forth between USD and BC gives more gain then the costs of the fees.
If it has something to do with the Futures (make them very attractive...) I don't know, but we will find out soon...
