Ok really bearish action in BTC has dropped it down to under 10,000. So where do you want to take a look at buying some if you are interested. My experience tells me that a scale in approach is best as it is highly unlikely you can pick a bottom and if you wait for the bottom to materialize you may be chasing it much higher than scaling in on the break.
This is a wild trade and price movements are enormous but one needs to start at some logical level. Current BTC price is 9285 and I would buy in 1/3 of my expected position here and 1/3 at the 8550 level if it gets there and the final 1/3 at 8000 if it gets there. This would be a long term hold type position not a short term flip trade. So I am not including a risk level. Should BTC take out the 7700 level a re evaluation needs to be done.
Best of luck on this.
