The older people will get an asset that is safer and well known. Not a risky less known asset. Hence they will prefer gold over bitcoin. But the younger will try to explore more risks and hence they have a lower threshold for buying bitcoin.
There are older investors into bitcoin but this number is small, specially fixed to those who are tech savvy.
Searching for something good in the crypto space does not make any sense. Rather buy bitcoin and continue buying it whenever the prices drop.
Future generations will be the ones that will truly embrace Bitcoin as the next "Digital Gold". Just wait until the "dinosaurs" become history (the "old class" Elite, the establishment, etc) and Gold will eventually lose its luster as a store of value. The world is quickly shifting into the digital realm. So intangible items would become more valuable than tangible ones. At least that's how I see it.
Bitcoin is finite/scarce, extremely-secure, censorship-resistant, decentralized, and portable. It has all of the aspects/properties of Gold (even better). I'm sure it will overcome Gold's market cap in the future. Just you wait and see. If we don't witness such an event, our kids or grandkids will. Hopefully, Bitcoin survives way beyond the last coin mined.
