In the strict evaluation of things, one wonders what percentage of that jumbo ROI was actually taxed. And if taxed, was the tax relatively fair when compared to other more regulated sectors such as real estate, solid minerals, etc.

While the above observations are debatable, the highly unregulated nature of the crypto space at these formative years also give room for a lot of market manipulations and rigging which only the few early adopters/venture capitalists benefit from.
