One way which might be a reasonable comparison would be comparing the price of the total amount of gold mined till now, to the price of the total amount of bitcoin mined till now.
It won't not be a powerful approach to look at both of the benefits since no one knows the aggregate weight of gold weight of gold mined since the begin or even the previous hundred years.

As far as esteem, both having their own particular significance, bitcoin is still ahead as far as esteem and is always expanding so regardless of the possibility that a value examination is done between the two it won't stay valid for long.
