Yes, might be but in future. main problem is many countries are slowing the process of cryptocurrency around the world. when all country will start supporting it openly only then we can see this kind of romantic dream that bitcoin will replace the gold.
The main problem of bitcoin replacing gold is its legal status around the world. As you mentioned, a lot of countries have started to prohibit and impose rules prejudicial to the existence of bitcoin. The process includes an imposition of taxes, stern rules and regulations against ICOs in country, country prohibition of any form of utilization, etc.
Another thing to consider, gold has been the basis of every country in terms of its currency value. Without gold, their currency will contain no value at all. Gold reserves actually reflect the status of a country and the value of their currency; it is purely on the economic side. If bitcoin were to replace gold, then countries must agree and view it as their main basis.
Gold is a natural resource and bitcoin is a crypto currency. Per my thoughts, bitcoin cannot replace gold
thus bitcoin and gold have their respective advantages. so we have to make the best use of it to be more useful and profitable. interesting what if we invest in bitcoin and gold, because bitcoin and gold have a high value.
Both of them have high value in terms of price but what makes them difference is their nature. Gold, in general, is tangible and is a non-renewable metal. Arguably, bitcoin also has a limited number of supply in the market. I doubt that bitcoin would replace gold soon as countries need to accept it first as their basis for their currency.
