Bitcoin made a lot of sense when I first read about it in 2011. Back then I feel like it was primarily used as an anonymous payment method. Think dark web/silk road type stuff. I certainly don't endorse that behavior, but bitcoin as a payment method made a lot of sense. Bitcoin makes 0 sense to me as an investment. It's pure speculation with no underlying intrinsic value. It's the Dutch Tulips 10.0 basically. And now…
"no underlying intrinsic value" How does that differ to investing in fine art, scarce wine, old/rare stamps and coins, limited edition/novelty items, historical artefacts, or even gold? There's loads of things that have kept value for centuries despite having no intrinsic value.
Not saying Bitcoin is worthless; it's a currency and it has it's uses, which makes it worth something. However, I think the belief that "it's scarce, therefore its worth something" is a false one and leads a lot of people to speculate wildly on it.
