It still surprises me, for someone with such insight and the math as you have, that you're seeing an inevitability to the future based on what has been.  You talk of the 'long-term trend' as if we know what it will be.  We only know what it has been to date and looking at the 'S-curved chart' as described so beautifully by James G. Angelo in what both you and he (and I) see as the early days it is volatile and there is much random unpredictable noise such that the formula defining the curve is very difficult to ascertain - especially with the gradient of the curve being so shallow at this juncture (yes, even at current growth in comparison with potential).  Surely we will only be able to give the S-curve its formula after the event?  Whilst your current calculations and projections may after the removal of noise turn out to be 100% correct I would venture it is a lot more likely to be incorrect, possibly by quite a lot.  There is a danger in having the understanding you do of math that you get to believe what is to come will nicely follow your formula.

Always remember:  This is Bitcoin - there is no inevitability!!!
