Fiat currencies will depreciate highly at some point. And then, governments' first choices will be digital currencies. But I don't mean the volatile cryptocurrencies of course. I mean the digital currencies that governments will develop. When it comes to owning Bitcoin, it is really a big advantage for its investor I think. Especially if you are a long-term investor, it is the best choice among all the cryptocurrencies by far I think.
Fiat is experiencing a high inflation right now which means the prices of basic commodities are rising, but leaving fiat's value in depreciation. So if you have put all your savings and investments in fiat, then you might see them less valuables in the future. It' will be better if you start prioritizing investing in bitcoin right now because it will be more likely to give you huge profits in the future as long as you chose to invest it in long term. Bitcoin may not guarantee sure profits all the time due to its volatility but at least you know its value will definitely move upward in the years to come, unlike fiat that is getting less value as time goes by.
