I think, Bitcoin is similar to WATER.
In the Nature, there is water in the clouds, not gold

Any opinions?

I don't know what you are trying to drive out, but there are no similarities whatsoever.
I can't clearly understand what he is trying to imply with those sentences lol. I can't find any relation to any of the variables given, bitcoin, water, and gold.
Isn't it water is abundant and it is 'natural'? While bitcoin is man-made and has limited supply. So I think you got your analogy wrong in the beginning.
Water is coming from natural resources we have, unlike bitcoin that follows a protocol and has a limited supply, gold that has been for ages and valued expensively. What's with the comparison between these? arrggh
