2) I prefer investing in bitcoin than investing on Gold. You can buy bitcoin worth 10 billion dollars and keep it on your wallet without even anyone noticing you have that number of bitcoin in your holding. But if you buy such number of gold you will not be at peace with yourself because a place of storage will be a problem for you . I have many other options to prove how important btc is, over Gold.
You can travel anywhere around the world with your Bitcoin in your wallet but can not travel with Gold,k but still need to sell it before you.
But I bet you that if you had 10 billion USD or a large amount of money, you would never dare to fully invest in bitcoin even if you knew that you had full ownership of your assets. Besides the guarantee of privacy and self-control of assets, the fact that our assets are 100% bitcoin also has risks that if we make a mistake, we will regret it for the rest of our lives.
Gold will be essential in that case as you will definitely need to diversify your assets to ensure your safety. Gold also has very good use cases and bitcoin is not perfect.
Let me just say, 10 billion in anything would make me nervous, digital or not! There's no way I'd go all-in either. Imagine accidentally losing the private key of the wallet or sending all that Bitcoin to the wrong address. One wrong click and it's adios to your savings! But Bitcoin's portability is definitely a plus. Gold is much bulkier and more difficult to transport. You need a large secure storage, anti-theft security measures, etc.
Maybe you're right - and mix is the way to go? Best of both worlds.
