This statement is so ironic to me I usually don't even know where to start.
You know what had no value? Beads had no value. Shells had no real value. Any money not backed by anything things like gold technically only has value because the masses see it as having value.
A dollar bill costs ~7 cents to make in reality.
If BTC has no value, then send someone else 1 BTC for free. That's how you would know it has no value.
Seems to me BTC used to be "valued" at 8 cents once upon a time. Lots of adoption has occurred since then so now it's value is ~$20,000.00. It's value could be less soon, it could be more soon. We'll see what we as a human race value it at.
Just facts here
