I pledge to spend my Bitcoins to buy goods and services I might otherwise buy with fiat 100% of the time.
If I cannot procure those goods/services with Bitcoin I pledge to request the merchant accept Bitcoins.
I promise on a stack of (insert preferred Holy Book choice here) to support 100% of the time the merchants who have the foresight to support Bitcoin.
I do this to ensure the true value of Bitcoin, the utility, continues to grow. And the true value of my Bitcoin holding does not turn to zero.
Signed (in blood),
Sage
P.S. Of course it goes without saying I exchange fiat for more Bitcoins just as fast as I spend them.
Who else will sign the pledge? Let's show the merchants just how short-sighted refusing Bitcoins really is.
I will take all your fiat since its pretty much useless to you.
