There is a distinction between pyramid schemes and ponzie / multi-level marketing schemes. Pyramid schemes aren't implicitly bad - they just mean the last "ladder rung" of the pyramid will lose on the promise of the scheme while anyone who got in before the last profit.

You expect to make a profit on the foundational principles of pyramid schemes. Someone will eventually, inevitably, have to not make a profit because the market of bitcoin will be fully saturated. At which point the value of bitcoin has to be reconsidered - it no longer would be poised to grow through increasing scarcity, so it would need to derive value through other measures.

Whether that happens in a year or a century is the gamble.
