What do you mean by these two comments? You're listing mistakes cryptocurrencies have made and these two are on that list.

Bitcoin is backed by fiat currency? Since when?

Bitcoin lacks a patent? Why does it need to be registered as an invention with a company?

I think you may misunderstand a bit how Bitcoin works (and call me out if necessary).

Bitcoin isn't backed by fiat currency. The reason people refer to the value in terms of fiat is because that's the currency that people use to buy and sell it. Bitcoin isn't backed or pegged or hinged to the value of a fiat currency. It's performance or existence isn't dependent on fiat currency.

Bitcoin is a project, creation, invention that isn't bound by any government. A founding principle is that it fills a void in the money system that's been lacking free access, support, and market. For Bitcoin to be registered for a patent would completely and directly undermine what Bitcoin is meant to be. It's meant to operate independent from any central entity (especially government). Trying to gain approval and protection to exist from a government would be the single greatest irony Bitcoin could achieve (and not for the better.)

If I've misunderstood you, please let me know.
