It's very interesting that the technical analysis seems to show how BTC has been building up towards the BTG fork. I think the announcement of Coinbase that BTC holder will get one BTG for each BTC provoked that overthrow. Now, it is my opinion that BTG is going to be a huge disappointment as people is expecting to get a BCH like effect, which I don't think will happen. And they are paying BTC too high. So I think you are absolutely right @haejin: whatever the reasons are, TA shows what happens.
