I think it is not burned, i think it was lost by users stupidity. But also how come people can send btc to a specified burn address. When in fact that address is already burned, the address is still active but not accessible? I'm a bit confused on what is really burned addresses. BTCBurn website got some concrete evidence that the address is really burned?
They're really burnt, as generating a private key to any of those addresses will take up more time than it is from the beginning of universe, and spend more energy than the solar system (maybe even the galaxy?).I have just read the article again and found there're misleading information. They said the block mined right after halving can't be spent, but output from block 210000 have spent here.
P.S. Why are there 13 BTC as fees in that block
