One of my subscribers swears by GBTC timing, but I don't follow close enough to concur or disagree. Last i looked at GBTC I was looking at the $6's for a bottom. For C of BTC, $5700-5600 is what I have using standard projections but BTC often extends in its fifth, and so can beat my estimates lower. Also, I have a large fib of high importance at $4700. I can't see a projection that far, but it warns that if we don't hit it now, we get a large B wave, maybe to $12K-15K and come back to $4700. Those bigs often matter a lot.
