Yes, cryptocurrencies, aka "currencies", are used for buying goods and services.
No no no. Cryptocurrencies aren't used for buying goods and services outside of extremely fringe scenarios.
People trade them like they do stocks. You can pretend that's not the case all you want, but you know it to be true.
I can't go to Aldi and pay for my shopping with bitcoin or whatever shitcoin you hold. I can't pay my bills with it. I can't go get a haircut with it.
All I can do is treat it like a stock.
Energy consumption is a great point if you ignore the material resource acquisition cost, worker cost, production cost, sundry cost, hardware cost, conventional debit and credit fees, service personnel cost, data centers, servers, and telecommunication network costs of conventional currency infrastructure
I'm not ignoring any of that. Crypto still uses far more, and to top it all off, can't really be used as a currency.
You cryptobros have been saying crypto will replace real currency any day now for years. It's not happening. Sorry to burst your bubble.
