He's right though. The number of people driving their cars to the nice air conditioned bank building every day globally, so they can sit there and accept your money uses a staggering amount of energy. Bitcoin's energy usage to secure itself is tiny in comparison. Especially given that it can be used to secure an infinite amount of value, with the same energy usage.

If you don't like Bitcoin's energy usage, then there are alternatives, like Ethereum, which now consume tiny bits of energy and secure similar amounts of value.

I also don't see Bitcoin as a currency. It is a commodity, like gold. You're looking at the price of BTC against USD, I'm looking at it like "How much can I borrow against it?" You don't go into the store with a nugget of gold and plop it on the counter, you buy gold because you feel like it will maintain its value over time. I can also leverage that gold by borrowing against it, the same with Bitcoin. That is how I can use it on a daily basis.

> But I know its value won't be cut in half by next week.

In the US. Other countries are not so lucky, should they just be stuck holding the short stick?
