I don't know how bitcoin will eat gold, but I hope that gold and bitcoin can work side by side and not interfere with each market because gold and bitcoin had a different market.
Bitcoin and gold are an investment asset that will become people's option to help them profit in the future.
But maybe bitcoin will have a chance to be the next digital investment than gold as the technology still develop and bitcoin can be adopted in all countries.
Gold will still be a safe haven for people who don't want to use bitcoin, while other people who want to have another investment type will try to use bitcoin.
Gold is still a safe haven. I'd say safer than Bitcoin. So if one is looking for a safe haven, I believe one should go for gold rather than Bitcoin.
But in terms of competition between the two, it cannot be avoided. It is impossible that both markets won't collide in one way or another. For example, you've mentioned about profit. Which would provide you a quicker and bigger profit? Is it gold or Bitcoin? Your answer would then determine where your money goes. That's one instance of competition.
Another instance would be whether which between the two would you prefer to own. If you buy $10,000 amount of gold, are you gonna be given real gold? And if you are, is it easier to own and keep than Bitcoin? If you buy Bitcoin, would you be given real Bitcoin? The answers to these question could be additional reasons why one would prefer one over the other.
People know that gold is a safe haven for their money, and they bought gold a long time ago.
Maybe people who invest in gold are not ready to invest in bitcoin because of the volatility.
Maybe bitcoin does not give a quicker and bigger profit in the short term, which is happening with gold.
But if we talk about the future, maybe bitcoin will have a big opportunity to give a bigger profit than gold.
What people search for the way to save their money is gold because many of them prefer to use traditional ways.
If you go to the jewelry shop, you will get real gold at $10k because that is what they know so far, and from what their parents told them.
But if people know about bitcoin and enthusiastic about the new technology, he will choose bitcoin as their investment.
So that will depend on each people itself.
But we are now in the digital world, which many people still do not know. But bitcoin will have its way to reach that person to join with bitcoin someday.
