Bitcoin doesn’t burn electricity. To produce it requires electricity, just like anything of value requires energy. Gold mining requires energy. That was a ELI5 explanation for you.
Of course, one would always see mining bitcoin as “burning electricity” as long as they don’t see why bitcoin is needed.
To understand that, you would need to understand the problem bitcoin solves. Which would require you to ‘see’ that there is a problem in the ‘money’
But that would require you to read about things like money, which everyone is cock-sure they understand.
It’s easier to say some random ass thing like gold conducts electricity, bitcoin burns it, which is more valuable?
