Cash Flow of Gold vs Bitcoin Miners

The five largest publicly traded gold miners generated total revenue in the first half of 2021 of $15 billion, while generating $2.1 billion in positive free cash flow!

The five largest publicly traded crypto miners generated total revenue in the first half of 2021 of $311 million, while burning through $461 million in negative free cash flow!

If Crypto miners can't generate positive free cash flow today at the peak of the Tether ponzi scheme... how will they ever do so when Bitcoin approaches its "supply limit" of 21 million? The supply limit will have to be removed or else nobody will have any incentive to mine Bitcoin.
