Gold and silver are solid coins in the same category of precious commodities. These investment instruments are as old as human history and as reliable as human history. I can always invest in them and never hesitate to do so. On the other hand, we need to unpack the concept of crypto in the topic title. I trust solid cryptocurrencies like Bitcoin and Ethereum as much as I trust gold and silver, and I invest in them as much as I invest in gold and silver. As a result, I don't see very sharp differences between gold, silver and Bitcoin.
