Ignorant people rant about the environmental impact of
cryptocurrencies. They don't know shit. How many wars were created over fiat
currencies and the power plays
of politicians and central bankers?
Fiat currencies are inflationary, so they encourage economic growth (at
what cost? At whose expense?). That inflation also attenuates the
indebtedness of states, it is like an invisible tax against the poor and
the financially uneducated.
Dumb journalists, central bankers and politicians try to hinder
financial independence and privacy with bans and biased news. They have
failed; they will not succeed. It would be like trying to ban precious
metals.
There are cryptocurrencies that are trash, that don't provide privacy,
etc., but you can't tar everything with the same brush. Moreover, the
environmental impact is minimal compared to fiat currencies. There are
cryptocurrencies that pollute more than others, of course. For those who
care more about the environment, there are cryptocurrencies that do not
use proof-of-work algorithms.
