The answer to this question will be much easier than it seems. I think that silver is a bad investment, because the prices of leaders in their field are quite predictable (the crypto world is bitcoin, the reality is gold and dollars), but I don't like silver as an investment at all. Then the question remains: bitcoin or gold? Gold is called a Safe Haven Currency, because in bad times smart people invest in it, because it is material and always valuable. But if the times are good, then everyone is invested in bitcoin. In general, we need to look at the situation on the global financial market, and decide based on this.
