I get that it can be convent. But why does it have value? As far as I can tell, it only has value if you find someone that believes it has value. Granted the US dollar exist based on a belief, but the US government is standing behind it. Not that that means what it once did, but we all agree it has value.
Why do the VISA, Mastercard, or PayPal networks have value? Think of Bitcoin as more of a “system”.
