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?
To answer your question, you need to remember that the value of gold, first of all, lies in the fact that it is stored by countries, and its quantity is constantly increasing. There are other uses for gold, which makes it not only a storage medium, but also a medium for and use in everyday life. Cryptocurrencies to start with gold in value, you also need to repeat the path of gold. But we know that countries are already thinking and working on creating their own digital currencies, and it is likely that the value of cryptocurrencies will only grow in the future, which is certainly very good.
