Government's of the the world have their national reserve in gold not in bitcoin and this delivers an explicit message that the trust gold have earned over the centuries bitcoin do not come close...
Well, we know how hard can be to store and hold gold. And if you let the "third party" do that for you, then you are at their mercy. One day they can just say "fuck-off" and not let you use your gold, I think we already have examples of that around the world. That can't happen with your Bitcoins, if you remember "12 words" you are the only one who has control over your funds.
I guess that "trust in gold" is dying slowly, it's like some "glory from the old days"... I am not into gold and I don't care about it at all, and I will say that new generations are more into digital things, and they know that "freedom" is not "freedom" if someone can control everything you do with your money, read banks and regulations.
I am more particular with diversification of investment about the two assets bitcoin and gold. Let's keep sentiment aside, a good businessman won't go all digital with his investment he/she will also diversify into real life tangible assets like gold or real estate no matter how conventional digital assets like bitcoin is taking a center stage at the moment. When we diversify investments we reduce our risks.
I don't know how you mean by the trust in gold is dieing as long as I know there are still innumerable investors that still holding on to gold as part of their investment portfolio's. For the fact that we're going digital wouldn't make gold worthless and except you planned on having a fleet of gold bars that's when you might have difficulty in storing, therefore handing it over to a third-party custody becomes your next line of action.
OK, I will follow you... did you diversify and do you have investments in crypto and gold? And if you diversified how much you have in crypto and how much you have in gold?
Let's keep sentiment aside and let's be open here... I don't have any gold, but I have some crypto! I chose the side, and I will not diversify in gold or some fiat, I can diversify by owning different coins, and I am doing that. I am not sure why you mention real estate, to get into some you need a big bankroll, many people can just dream about buying one. It's easy to talk, but it's hard to get into it.
So, you can try to sit on two chairs... and that can pay off one day, or not... we will see.
