ETHUSD very risky short

Looks like "The Falling Knife" on the 1h chart. I'm trading the second part of the knife.
On 1D is a breakout from the "Reverse Flag" but with low volume.
Also ETH standing on 1D chart on a very strong support-level.
The Bollinger Bands are very tight. Big explosion ahead.
The position is risky, but if goes right - 10x RR.
