You have this doubt because you still have faith in government issued money, so you think dump the coins for some fiat is a nice move. I guess Satoshi does not have such faith, it is clearly written in the genesis block
Instead of arguing the actual points at hand, you attack me personally, by stating that I am dumb enough to trust fiat.
I have no intention for any personal attack, and I don't think it is a bad thing to have faith in government issued money. Many people include myself have certain degree of faith in fiat money, because you can use fiat money to purchase anything domestically. But bitcoin can give some more faith due to its transparency in money supply, so dump bitcoin for fiat is not necessary until you definitely need to spend some to support your life/business/project
