That's a good idea but it's old, and that's the idea of the old people who didn't have bitcoin before. Now that things are different, we have a different kind of non-physical assets with limited supply. So buying Bitcoin will be quite reasonable when you live in a world of technology, gold will not make us as much profit as bitcoin. that's what I'm sure of because the price of bitcoin is more powerful now than Gold, like the Iranian rocket launch on the US base.
