It's true that the dollar and Bitcoin are fundamentally different, but this comparison can also be instructive. The dollar is a traditional currency, but it is subject to inflation and the monetary policy of the Fed. On the other hand, Bitcoin, while limited in supply, is also subject to its own volatility and risks such as hacks or regulation. Claiming that Bitcoin is a hedge against inflation is debatable, as its history shows strong price fluctuations. Therefore, it is essential to consider not only the differences but also the economic implications of each.
I terms of security, for sure the dollar an be said to be more secured, not because it is not subject to hack or other visis, but because it is government own and the central bank can print as much dollars notes as possible, unlike bitcoin that have a limited supply, but yes also you have a valid point on the view that both dollar a d bitcoin have their own unique differences but in all we have to make one thing very clear, bitcoin and dollar are two incompatible comperable viraibles object that exist a in the same financial environment and their act as alternative to each other and not a replacement for each for whatever reason.
