Although gold has had great performance the last year, its long term performance is at best equal the S&P. The longer the time period the worse the comparison gets. Gold also has the issue that as prices rise more will be mined. At some point supply will meet demand and returns will probably be below the S&P.

The S&P return over 26 is 8% per year and over 14 years is 13% per year. 13% probably represents a maximum for the S&P because over time interest rates will probably rise. In that environment S&P earnings will be under pressure from higher costs. Not all costs will be able to be passed onto the consumer resulting in lower earnings.

Bitcoin mining has produced about 95% of all bitcoin so for all practical purposes bitcoin supply is fixed. Bitcoin is used as a currency in many parts of the world or at least a store of value in an inflationary economy. Bitcoin is also a form of energy. The point is bitcoin is real. In an environment of higher interest rates bitcoin could be seen as a safe haven and an alternative investment class.

For those investors that think well of bitcoin, it is probably the best choice for storing the profits from TQQQ over the next 25 years. The last 5 years bitcoin had an annual return of 28% per year. 40% bitcoin in the Stars model would increase the performance by 6 percentage points per year.
