Lol wat??
You don't have to believe in fiat, it exists and it works for day to day transactions. Don't know about its future.
agree. I myself never think to believe in fiat or other currencies. just use what are available to use as long as they're legal, or no one forbids us to use it, or the advantages are not too much.
fiat itself is not forbiden, is legal and currency. so just use it, don't need to believe in, that's all.
We believe in fiat and we believe in bitcoins but fiat is more secure because it is widely use by the people of a certain country as enforced by the government, if we don't believe in fiat we cannot survive as we don't have something to spend. However, the future is good for bitcoin that would make the fiat also affected in an negative way.
