So if the trend is correct and if it continues, now is the time to buy.
If we go from .50 below trend to .50 above trend in the next couple months...

Either we do and the trend holds, or we go to only 0.3~0.4 above trend and we may need to slightly readjust the curve to fit again.
If we start having waves of -.5 to +0.4 it means the mean is not the mean anymore. Which could either mean adoption is slowing or the mean that was drawn here was too optimistic.
Hopefully we will hit +0.5 log delta though it would mean a nice value for bitcoin. Depending on when the peak hits it would be somewhere around $6000~8000
