The crypto market has a high level of volatility. Anyone who is about to make an investment needs to have a good understanding of the volatile market. Now the question is, even with volatility, will you still choose to make your investment in fiat through bank savings with regular monthly interests or rather make your investments in crypto where you hold your asset and still have the opportunity to save and make monthly interest?
It simply does not make sense to invest in fiat currency for me. I live in a country where my local currency value was 78 BDT per USD about two years ago. Now it's 120 BDT against the USD, and I am afraid it will increase further. All my holdings are in Bitcoin at this moment, and I will accept the lose as well because it has the potential to give me 2x profit in the next couple of months.
I can cash this Bitcoin anytime and If I sell my converted USD for Local currency, I will likely get a better exchange rate because of the inflation. Things could be different in your country. But investing fiat is big NO NO from me.
