As you can see in this daily chart, TD reached 9, which in the history of Bitcoin often times indicated a bigger correction. We also held this 8100-8300 level for a longer time now and didn't manage to get a new ATH since 2 days now.
This is not guaranteed of course, but i would personally not hold any longs over night right now. Be careful with longs over a longer period now, i am personally short, until we do not fullfill the TD seq. It isn't looking good for BTC right now tho.
BCH dumping could be a factor of BTC not breaking down tho. We will see how this plays out.
