Because could bitcoin represents a value reserve or acts as a "digital gold", really could it change the world in a deterministic sense?
The answer to this is obvious: yes. Since bitcoin is a mathematically founded protocol with a predictable rate of inflation and built-in scarcity, it acts as a store of value. Bitcoin is also more portable than gold and is more difficult for outside governments to confiscate or place sanctions on.
Although bitcoin is more portable than gold but gold still better than bitcoin. Both are very worthy. Bitcoin has many advantages that will help many people. It can become currency and asset at the same time, the value of it is tend to rise. Bitcoin theoritically is appropriate as a store of a value, it has limited amount, uncounterfeited, fast in term of transaction and many more but since there are many hoarders or what we call whales who influence it price in the market then for now it risk become bigger.
When you said gold is still better than bitcoin, to me I expected you to list out all the reasons why you think gold is better than bitcoin, but after reading the remaining part of your comment, what you statement fully interpret to me is that Bitcoin benefits far outweighs that of gold which makes it better than gold.
Bitcoin is just at its early stage for now, its just barely 10 years old, while gold is almost over a thousand years old now, and everyone knows that bitcoin is yet to fulfill that aspect of its benefits of having it as store of value because of its high volatility, but in future, bitcoin become far more better than gold when the rice becomes stable.
