The question IMHO is not IF rather is when. Its really hard to know when it will start declining and how far. But the RSI divergence it's really notorius. I'm sure other oscilators are showing the same stuff.
Rmember Ascending triangles most likely will break on the upside, but need to wait for break!
BTCUSD bellow 6000 is possible going to 4000. Sell Stop at 5900, take profit at 4100, stop loss at 6900
