Even though they have established bitcoin as a legal means of payment and transactions, El Salvador still uses fiat currency as a means of transactions. But the advantage they have is that bitcoin is free to use to buy anything because bitcoin is legal as a transaction tool there.
Bitcoin transactions can cost up to $30 US dollars. Bitcoin is absolutely
not free to use.
It's the very opposite of free, actually.
I remember those days when I am still new in crypto that I see and happen to experience that bitcoin transaction fee is less than a dollar , but now never that i happen to experience this low fees and hoping that this will come to happen again in our time now specially that now bitcoin is continuously growing year after year.
