gold has value because it is useful. it is not just an asset you invest in and nothing else. gold is being used in thousands of different places. in different amounts and shapes from big size in jewelries to tiny nano particles used in medical technologies.
bitcoin has value because it is useful too. it is not just an asset. bitcoin is useful because it is a currency which is decentralized. has high security and global. of course being cheap is desired but sadly for this short period of time we can not have that. hopefully we will in the near future again like we had low fees before.
Gold and Silver have unique properties, such as being the highest conductor for both heat/electricity. Silver is better than gold slightly in that aspect and also has antibacterial properties.
Agree bitcoin has its own unique properties, in places during the GFC people invested in bitcoin to avoid letting the banks steal their money.
