I don't protest the obvious. There's little discussion about the harms of global warming in general; this is a generally accepted fact, at least to most people I engage with. The same can not be said about cryptocurrencies and their harms; this is an argument worth having, precisely because people have not yet fully acknowledged the problems. Also: it's remarkable that you've so fully analyzed my personality in 5 minutes.
In any case, to reiterate my counterpoint (which you have not disputed, but given your ad hominem I assume you don't agree with): estimating at least an order of magnitude impact of bitcoin isn't that hard, so your suggestion that it's hopeless to compare somebody streaming gangnam style with a bitcoin transaction is unfounded. One can compare bitcoins environmental impacts with other environmental impacts.
