it produces 67 times more hashes per second than there are grains of sand on Earth.
It's indeed powerful, but that's a bit too much. Things such as sand are uncountable, and that's not only because of its size but also because it exists in very large numbers. The number of hashes generated by Bitcoin per second can't be higher than the amount of sand that exists in the deserts worldwide.
It's an exaggerated comparison.This is so so amazing and incredible. another amazing fact is that in terms of raw operations per second, it is 500 times more powerful than the world's most powerful supercomputer.
Yeah, because there are millions of powerful pieces of equipment called "miners" powering it, we call the process "mining". I hope you understand and realize that Bitcoin is not a system such as a computer or something, but it's a system that relies on computational power provided by systems, a.k.a miners.
