Earlier quoted context omitted.
Another critical difference is that there are commodity uses of gold. The price of gold will never go to zero ; it might go to $100 or $10 per oz if all speculation and hoarding were removed from the market but it wouldn't go to $0.
Sure but what's the importance of that fact? If I buy an ecoin at $1500 and it goes to zero and if I buy gold at $1510 and it goes to $10 it's the same loss. I guess what's the real importance that gold has a floor which is marginally above zero and bitcoin doesn't if both of those floors are far below the current price level.
And, uhh, if you don't know why having a good idea of your potential downside is useful when investing, maybe consider finding a trustworthy financial adviser?
