> Bitcoin has been mined for over a decade and never came even close.
The problem with using past performance of the Bitcoin network as an indicator of future performance is that the exponential nature of halvings means that each decade is a vastly less subsidized environment for the network than the one that came before it. Over the last decade the network has given ballpark 4.2mm BTC to miners for their services; there are now about 1.7mm BTC available for miners for all time.
