I always sell into strength. And if I think the run is not over, I buy it back cheaper.

Yeah, the USD values are the same... BUT I found that... long-term you want to trade for more Bitcoin... for the exact reason we are talking about (i.e. compounding gains).
However, there are so many PUMPS that I quit worrying about if a trade brings me down 15-20%. I make it back and go beyond over time.
I quit trading USD; it's done me little good. Too much volatility AND what I realized is that you can't buy back USD cheaper.. unless it's Tether... but that might only go down by 0.1%-.5% (which is not really enough to even cover broker fees).
