I largely agree with the rest of what you say in your post.

I want to harp on this above highlighted point for a tiny bit. 

This 9.2% target sounds like one of the underlying theses and agreement points of the hosts of the podcast "Bitcoin Uncensored."  I think that they make a lot of good points when they argue that financial advisors cannot beat the overall performance of the stock market indices (which averages 9.2% over the long term), and investors should expect that they are doing well in their investment if they can average such a return, and they are unlikely to be able to provide long term evidence of beating such 9.2% performance.

I don't really know enough about the price performance of a large variety of budding industries (such as telephones and cars and computers), but I have my sense that when you do pick the right budding industries in which to invest (which could be the case with bitcoin that it is the right one this time and in these circumstances), you are going to get periods of exponential and irrational growth periods that exceedingly outperform any other investment, including indices. 

One of the difficulties in picking such is that we may be able to pick the right investment once in a while, but if we repeat the experiment over and over we cannot expect to continue to pick exponential growth industries on an ongoing basis. 

Anyhow, I doubt whether the 9.2% goal is realistic (I think it is too low of a goal), especially if bitcoin has another exponential growth period (like it had about 5 previous times), which is quite plausible given its currently ongoing low market cap (in comparison with its various fundamentals) which seems feasible that bitcoin is going to reasonably be able to significantly outperform 9.2% for the coming years and to perform a 10x or a 100x increase in market cap in order to become much less susceptible to volatility and manipulation... market cap growth seems like a necessity for this particular sector, whether we like it or not...
