Gold are the mean of exchange for thousand of years. It hard to be replaced because some people think that gold are much more secured than bitcoin which is too risky.
If I had the chance to do this in 2009, and hold either Bitcoin or Gold from then till now, I will choose Bitcoin without having to think twice about it. As of now, Im still choosing Bitcoin and not gold, I need money, Im not preserving the ones I have, and getting stuck at the same.level. when I want preservation, I will go with Gold, but as of now, thanks! 👍
