i personally never seen any person getting rich from just investing in gold but i've seen plenty become millionaire from investing in bitcoin at the right time and at the right moment.
thats the difference.
If you look back at the history of gold over the past thousand years, you will also see that the value of gold has also increased significantly compared to decades ago. That proves there are many people who invested in gold and became rich, but because you were not born at that time, you never know who became rich by investing in gold . Before gold became as big as it is today, it also had volatile prices and bull cycles, you have never read about its history, so you don't know about it.
Gold is an old asset and has reached a level of stability so comparing it to a new asset like bitcoin is quite lame. Just as many people will compare bitcoin to altcoins, many people invest in altcoins because they believe that bitcoin will no longer be very profitable. Bitcoin still offers significant returns compared to traditional assets, but there's no denying that bitcoin's returns are getting smaller. Do you see bitcoin rising millions of percent or thousands of percent these days? That happened years ago and now we will only have x10, x5...and they will get smaller and smaller as bitcoin gets bigger and bigger.
So gold will still be a priority compared to Bitcoin. Bitcoin does have another side that may be much more profitable, but because its value fluctuates greatly, some people are worried about investing on a large scale. And I also suspect that so far the development and interest in Bitcoin is also increasing.
