If we consider financial freedom as the absence of any intermediaries in transactions, which were usually banking institutions, then indeed, cryptocurrency in this regard helps to achieve such freedom. However, if we consider it as the ability to get enough money with the help of cryptocurrency to feel independent in order to satisfy our material needs, then the situation is much more complicated. Yes, those who acquired bitcoins, ethereum and other top coins at the then low prices in the early stages and held them for a long time made a good profit. But this does not mean at all that this will always happen in the future. Cryptocurrency is very unpredictable in terms of price.
Cryptocurrencies are investment instruments like stocks or forex, all of which are unpredictable. I've seen many people achieve financial freedom by investing in the other 2 markets, there's no reason why crypto can't. All the work or investment that can help us achieve financial freedom, all by ourselves and not because of the cryptocurrency or the work we do.
I have a sister who is an accountant, and she said that the accounting profession doesn't make much money, and her salary is meager. But meanwhile, my company's bookkeeper used to make several thousand dollars a month. Therefore, there is no profession that does not make money, it is just that we do not know how to exploit it effectively.
