It's by the greediness of people, even though money helps you to have a good living.

Just in the bible says (1 Timothy 6:10) For the love of money is a root of all kinds of evil...but money answers everything.  

I totally agree with you in choosing GOLD. Gold has been here ever since and will be here still.  

I wonder, what would happen to those who totally invested on bitcoin against gold when the time comes when the entire btc currency system gets wiped out?  

Everybody knows about gold but not everybody knows about bitcoin.

Gold is accepted anywhere which means gold will never lose its chance against bitcoin.
