Gold is tangible. Bitcoin can aspire to tap into the gold market sure, but gold is still a better store of value because it requires nothing to exist. Bitcoin will always require electricity.
Tangibility is actually an undesirable property. Time will show everyone because superior currencies will win in the end.
the industrial revolution changed the face of this planet, the way we live, the way we think, work, etc. the digital revolution is of the same impact. and now the digital revolution gets directly monetized. all the wealth aquired by/since the industrial revolution can go digital, and some will. cryptocurrencies are fueling the digital revolution part II. gold and silver are ok, but they are no gamechangers.
