Digital Cash, Digital Gold simply wouldn't work based on the simple narrative of that Gold can't really be used as cash in anyway in person at all while cash can be used to buy things like it's meant to do.
Well i dont think bitcoin is either of this .because 90% of the people use bitcoins for earning ,that is sell the bitcoins when the price is high.Bitcoins being used for groceries is not being widely used,if used in this manner will change the face of the earth in many ways.
Well if it has the ability to effect the changes you're talking about then it is a digital gold yet to be mined and refined for people to see its value. I think it's both digital cash and digital good because it's electronically operated yet has semblance of both cash(fiat) and commodity (gold).
Mining Process is something that I wouldn't really compare as one is a computer solving problems to confirm legitimacy and another is ACTUALLY MINING with machines and such.
Maybe sometimes bitcoin looks like gold, because it has a high price, but bitcoin also can be said very easy to get like cash. Maybe bitcoin is a combination of both, so can be said bitcoin is cash and gold money depends on the use.
Well, you could probably say Bitcoin is like a ton of other items due to the similarity in price. Wouldn't use that to call them similar It's cash bud.
