I feel that although Bitcoin is now regarded as digital gold, its market value does not exceed the total investment value of gold. The current price increase of Bitcoin is due to the characteristics of Bitcoin, distrust of banks and belief in Bitcoin. Most cryptocurrency investors want to profit from it. Although Bitcoin is risky, there are more or less risks in any investment field, even gold is also volatile. After experiencing some crises now, it is clear that Bitcoin has become a safe haven for people.
