I think the only reason why some people call Bitcoin, digital Gold... is because it was designed to act as a store of value, not because it is actually a store of value. (timing will more or less determine, if it was a store of value for the seller)

Yes, it is virtually mined like Gold and the software emulate scarcity with the Block reward that are halved... but it does not guarantee a constant increase in the value.... as we saw with loads of previous dumps that crashed the price.
