it has both the property fo digital cash, but also a store of value, because digital cash would not have any store of value, all the fiat currency are the worst thing to hold for a long time, you would only lose money
bitcoin it's like gold that was turned to cash and can be used far more easily than carrying gold around, the similarity is also very obvious, like the mining aspect, probably satoshi was inspired by a variant of gold that do not require trust and was decentralized
Without a level of utility value, bitcoin cannot be a store of value.
what do you mean , bitcoin is accepted in many shop, therefore there is a utility and consequently a store of value
to me i think bitcoin is a digital cash, as we have the opportunities to use bitcoin for online shopping while in some place we also have the facilities to use bitcoin for shopping in our local shops without changing it in to fiat currency. although i most of the areas the facilities of bitcoin to use it as fiat in local shops is not available and the reason is that there the users of bitcoin are not enough so that they can attract the shopkeepers to start accepting bitcoin for shopping, but still we are hopeful that when the users of bitcoin will increase there then the shopkeepers will start accepting bitcoins  for shopping.
