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.
We can take that gold has been served the mankind very well from the past until now, but we are now in the digital age where rapid innovation takes place and we should take advantage of the technologies that are worthy enough to help us make our lives easier. In terms of acceptance and adoption, there's not much issues concerning recognition by humanity as cryptocurrency is not forcing itself to be accepted by the people. The only obstacles that it has is about being accepted by most government. It lacks support in some countries that makes it hard for crypto to be further develop.
