Gold is good to hold value and purchase power. If you are rich, you need only this (to stay rich), and gold is safer.
If you want to invest in something highly risky that can pay a lot (or go to 0) bitcoin is the right choice.
I agree that you can buy some ounces of gold. But it will never change your life.
Rich people don't invest in gold but rather prefer diamonds or platinum. Else they just buy gold in the form of ornaments.
There are hardly many bitcoin users now and hence we can't even compare them with the users whom own gold as I guess there must not be any household which doesn't own gold or small ounces of gold.
For me, I prefer buying gold more than BTC as the former one holds more value than the later.
Platinum is classed as an industrial metal and diamonds are a terrible investment.
Why is diamond a terrible investment? The false monopoly hence false value of the stone?
And platinium may be industrial metal but it's worth hella lot of money ^^
It seems even a better investment cause it's more used than gold! So the supply is always decreasing.
