Gold still has that value even though it’s price has been inflated and corrected many times.
Bitcoin on the other hand has no real world value outside of crime because it never evolved to a real currency. Which means that the only way to gain a net value on your investment, is for orher people to come in and buy bitcoin after you.
Which means you’ll also have to sell it before those people too.
I’m not telling you not to buy bitcoin. It’ll probably go much higher than it is now, but it will some day go to zero because it lacks any innate value.
