Exactly, as the percentage changes, the money needed to push in either direction will grow. We could see big fluctuations in USD price that don't mean much in terms of percentage. A 30$ rise or drop will mean far less the higher the price goes.
This, in case anyone didn't realize is why log charts tend to work best. I much prefer them to those max-high, min-low charts which tend to magnify minor fluctuations when things are steady.
I hope 100 holds off a little though. I have things I'd like to do before it gets there
