Now a coin everyone mints at the same rate, would be legit.
Unlimited supply, inflationary currency. I think I've heard of that before...
It is limited to when you die you stop earning it.
This is the wrong sense of the term
unlimited here. When you die, it doesn't mean the injection of new supply also dies. Your death doesn't matter at all.
And is a unlimited supply so bad? fiat seems to be doing just fine, literally the measurement of bitcoins worth.
The fact is that fiat is not unlimited. The creation of new money is based upon a strict set of criteria. It's just that it is being abused. Fiat is extremely susceptible to abuses most especially because it is being under the control of a few very corruptible personalities. The rules are not hard-coded. It can be bent on whichever direction the whims of these people prefer. That's how Bitcoin is born, as a reaction to it. Or, if you prefer, as a solution.
Really it is a limited and unlimited supply, unlimited it can never be mined out so future generations always have some and don`t have to kill each other to obtain it, and limited that you stop mining it when you pass. A supply we have never tried before.
People always kill each other. That's true even before the first form of money came into being. Away from money, people kill for some corn seeds. So, don't bring it up.
