Apart from being an investment platform which was actually not the primary purpose of creating Bitcoin, do you know that Bitcoin is used as a legal tender? If yes, why then do you think Bitcoin is just an asset and speculation? Bitcoin demand now might not be as high as that of gold for some reasons and one of the major reasons is that gold have been known to humans even before money came to existence so gold is literally known by everyone as a good asset for investment but the rapid growth of Bitcoin as a digital asset project since the creation in 2008 should tell you that the future will favour Bitcoin more than gold. Bitcoin is a digital asset than can be easily transferred from one place to another in less than 5 minutes but gold transactions aren't that seamless and considering how digitalized the world have become and still becoming, it's obvious that Bitcoin in the future will surpass gold
