Goldman Sachs - which recently became one of the many institutions that changed its tune on Bitcoin and cryptocurrency - can be right. The real physical gold is really more of a store of value or a safe haven and that is why even if no one is really using it as a currency it remains to have a decent marketcap value as compared to Bitcoin. Now, one problem here especially in the eyes of the gold investors and buyers is that Bitcoin can be so volatile at times, unlike gold. However, if we take this volatility away, I don't think it can be as exciting as it is now...it will just be another boring asset on the market. Now, which direction Bitcoin can be taking that remains to be seen.
