This clearly the proof. But for traditional people will always say that gold is better than bitcoin. But for us, we can earn bitcoin as easy as it is than gold we're only talking about the money but for me bitcoin is better than gold. You can't earn 2k worth of gold in just a week. For some situation, gold can be robbed bitcoin can't. Though your account can be hacked or scammed you just lose your digital coins it can be easily earned again than gold.
There is nothing you can do to convince people that follow tradition, to them something is better just because it has been tried by several people before them and while gold is a good investment there is no doubt in my mind that bitcoin is the future.
