I would never put Dollar and Bitcoin in the same category. Dollar is out and out fraud, whereas Bitcoin is a far more subtle bait.

Bitcoin gives us an idea what a freedom currency might look like, but by itself it is missing some crucial elements to become that. There are many ways to approach this, but the best way for those who can understand technology under the hood would be to understand the history of its codebase and the forced tradeoffs that were inherent to the technology.

I highly encourage reading this article that explains this trade off.

Effectively Bitcoin required a tradeoff between speed, cost and decentralization. The SEGWIT2 fork specifically demonstrated how the community was forced by the money interests, against the wishes of original core developers, to compromise decentralization. And still the speed and cost are nowhere near what it should be for a freedom currency.

No blockchain technology (atleast that I am aware of) that exists in public today is suitable. Now if you consider that making the cryptography quantum proof is absolutely essential if we plan on using it for any length of period, it becomes obvious that the real blockchain, whatever it may be, is yet to be unveiled.
