It will takes a lot of time, sure, but to say it impossible while at the same time saying crypto is new is a bit too soon imo. It might change, it might not. As you said by yourself, crypto is new, very young compared to gold, but what happens 100 years later or 1000 years later, we don't know. Gold might be out of dated by then and crypto might replace it, or not.
Gold outdated? You've got to be kidding me. Gold has been serving some form of useful utility for thousands of years and there is no reason to think it won't be the main asset in the world in the following thousand years.
There are too many moonboys wasting time behind their desks staring at the crypto prices all day.
