What you say can indeed come true, if we see the popularity of Bitcoin continues to increase and more and more people are starting to choose to invest in Bitcoin over Gold. Moreover, millennials have started to focus on all things digital, then Bitcoin has also proven to be more profitable than Gold.
So indeed as time goes on there is a possibility that the demand for Gold will decrease. For now, investing in Gold is still safe and profitable, but we don't know what will happen in the future if we see Bitcoin's development is growing rapidly. Moreover, if many countries start to make Bitcoin a legal tender, many people will focus on investing in Bitcoin compared to other assets.
Millennial is just one aspect of it, we have now Z generation that grew up with bitcoin being a good and big thing. They do not remember the period when bitcoin was seen as a bad investment and all those talks about how it will be zero. Right now anyone who is 20 or so or even maybe younger thinks that bitcoin is this, the current thing, but they do not remember 10 years ago, or even 5-6 years ago when people were mocked for being interested in it.
This means the more we live, the regular it will become and crypto will be something that everyone will be using not only because it is a great thing but also because they have lived with it all their lives. Think about people who are 10-12 year old right now, when they are 20+ in 10 years they will be adults who lived in an age bitcoin was a thing, never seen anything before bitcoin, their birthday is younger than bitcoins.
Most people, especially the younger generation, are lazy to study history. So what you're saying does make sense, because the younger generation
will definitely not know how the history of Bitcoin, they are just crazy about advanced technology. For the younger generation Bitcoin is a normal
thing, so it is not unusual for the younger generation to invest in Bitcoin. We know most of the younger generation really like freedom, knowing
Bitcoin cannot be controlled by the government, it will increase the enthusiasm of the younger generation. So in the future the Bitcoin adoption
process will be faster, so collecting Bitcoins from now on is the right decision.
