I have thought that one key advantage crypto (bitcoin, litecoin, Dash, monero etc.) has over gold is that its supply level is fixed and transparent, but can this or features make crypto more valuable than gold?
I think this is not suitable to compare gold with cryptos. Because both are asset though but still both have different features. Crypto has more risk than gold. crypto market is valuable but not stable . Gold is one kind of stable asset . Both are valuable in their own way.
Yes, that's right, it all depends on each individual. What kind of investment does he like? If people like challenges with big risks but big rewards, crypto could be the choice for them. However, if they only want to invest with a small risk and only aim to keep their assets stable, gold is an option for them. So they can't be compared because they have their respective advantages.
