Both of them have many advantages that can be utilized by many people, so that something that has enthusiasts in society will not be replaced and they will forever go together and of course will continue to grow because that is what will happen as a store of value.
The freedom of movement with bitcoin is the biggest advantage if you compare gold and bitcoin as a store of value. Gold is a dominant store of value for centuries and you can really trust them and that cannot be said about digitally created store of value in the eyes of many and that is hard to change,
I don't think of this much, about the replacement and all that stuff, what do you think of bitcoin? A messiah? that will just make gold and fiat disappear lol we still talking about the supposed to be replacement of stuff in here, what's worst is that you giving a full blind trust with bitcoin that is decentralized, uncertain and volatile. Is this what an asset should be? a 100 today then 0 tomorrow? I don't think so.
may be the next generation will consider differently.
Bitcoin was an addition, it may grew differently as what its name says 'currency' but it is what it is, an investment just like gold, a thing for storing of value. I agree, the next generation of people will consider these things differently, and I think they will just go with what's on them now.
