Gaming is the sole demand for all consoles and GPUs produced in the world. Those devices alone consume a lot more energy than Bitcoin miners (by about an order of magnitude).
Gold and Silver are extremely expensive to mine energy-wise.
The banking system is amazingly expensive to run. Not only it requires lots of buildings and transportation for millions of workers, it also requires a lot of computing resources to be run -- without even guaranteeing you can withdraw your money from banks, and with your money there being corroded due to inflation.
Bitcoin, in comparison, is actually pretty "green" once you consider the value it provides: a distributed ledger with 10+ years of operation and no flaws/attacks detected, meaning it's the safest store of value known to mankind, while not being under any control of any organization or government.
In any case, even if your point that Bitcoin is "evil" as it requires "too much energy to run" is true, what are you going to do about it? Feel free to short Bitcoin in a futures market, and leave all your wealth allocated in assets associated to fiat currencies.
Bitcoin has maintained at least 60% market dominance year-over-year since its inception (averaging 75% all time dominance). Ethereum (which can be profitably mined using GPUs) has currently 15% dominance, with most of the other top 15 coins not being PoW (except for Litecoin, Bitcoin Cash and Dogecoin, from which only Bitcoin Cash can be mined either with ASICs or GPUs). Also, Ethereum is in the process of moving to PoS.
What cryptocurrency mining is mostly about is entirely irrelevant to either the claim that GPUs, and the power thet consume, are used exclusively for gaming or the counterclaim that, on the contrary, significant sources of GPU use outside of gaming exist, including cryptocurrency mining. It doesn't matter if the coins for which GPU mining is viable are a much smaller share, by whatever measure you care to use, of the cryptocurrency space than Bitcoin, what matters is whether or not mining them (among other non-gaming uses) is significant in the demand for and use of GPUs.
Which it is, which is why Nvidia has recently taken steps to actively cripple mining on some gaming cards so that thet can actually reach the gaming market.
(GPGPU is also a thing, and non-gaming display acceleration; the idea that GPUs are only used for gaming is ridiculous even beyond the cryptocurrency applications.)
Also: how many gamers are there compared to how many crypto traders? It's not a meaningful comparison.
You should compare Bitcoin to some aspect of finance that is similar sized, e.g. a single bank with similar transaction volumes, or something like the Bank Of England CHAPS network, which has about half the number of transactions, but 30 times the total transaction value.
