Oh, and so many people "who are in control of it" have too much of their own money invested into it to allow it to fail.
What is the floor price of Bitcoin, once you eliminate all speculation/hoarding?
Gold has use value in that even if the commodity speculation activity drops to zero, I can still turn the gold into jewelery and sell that. Or I could sell it to somebody who needs it for industrial purposes. Heck, I could sell it to the people who put gold leaf on candy.
Bitcoin has no such intrinsic floor. It only has exchange value. If people stop accepting it as a medium of exchange, you're left with bits. Bits are approximately free.
Commenting against BTC is sure to get you down-voted.
It's ok though, it's just one of many HN quirks we're all used to :)
I own 1 share of a SP500 ETF. That gives me an actual fractional ownership of Apple. That gives me an actual cut of the dividends of real american companies. It has an actual meaning of what you own.
What does 1 BTC give you? What is the fundamental purpose of a BTC?
Tulips went up in price too, but they were not a very smart investments. Tulip chases do not win in the long term.
Owning a BTC is the same as owning a dollar, functionally. The main difference is that dollars, on the whole, tend to lose value, and that BTC tends to gain.
One fundamental of investing is that stocks represent an economically productive asset. In contrast, commodities just sit there. If I buy a chunk of a company, that company is working to become a bigger, more effective, more value-generating company. If I buy an ounce of gold, it stays an ounce of gold.
Index funds represent a broader bet still. Because they're composed of many things, volatility is lower and you're betting on whatever the common factors of the index are. So buying an SP500 index fund could easily be said to be a bet on the American economy.
And in many ways, Bitcoin is worse than gold. The historical value of gold is known. Bitcoin is new. Gold's floor price is set by the practical use value of it, both industrial and decorative. Bitcoin's floor price is that of bits. That is, zero. The gold market is broad, with producers and consumers all over the world, and open markets in many countries. Bitcoin is effectively controlled by a relatively small number of people and requires careful long-term cooperation of those people.
So it seems pretty obvious to me that Bitcoin is much higher risk. Which can mean higher reward. But as anybody who has shares in a failed startup knows, higher risk doesn't guarantee higher reward.
