9/20/17 update: I haven't updated my GBTC bitcoin tracker in a bit since it has been so volatile. The "lower lows" ($481) and lower highs ($759) have been pretty "obvious" since the all time high of 1064.95 was set however. A move through $759 would "likely" prove deadly to GBTC tho. Even if it doesn't trade thru there the prospects short term really aren't that good. Now at 723.90...don't do it bitcoin loonies...it'll be much better for you if you just panic! :O
