In any case, gold was valued throughout the entire existence of mankind. I think that gold has proven its worth, while cryptocurrencies still have a lot to go through, including not only legalization, but also real recognition by humanity.
Gold has proven its worth really but I think that it is already getting too old, and needs to be replaced by a digital asset and this is where bitcoin will function perfectly, as a digital asset, After all government claims that bitcoin cannot be a currency, and if they dint want it has currency, they should not worry because we have got that one too covered, it can also serve as digital store of value that would later replace gold in the future.
I know that there are going to be so many people that will doubt this, but time will tell, as bitcoin keeps growing, most people you see prefers to just old it than even use it and I think because it is easier to access than gold, people embraces it a lot, and this is why I believe that in future it could replace gold.
