The way I think of bitcoin and cryptocurrencies is as a huge thing looking for a ledge to hold on to. It's pretty likely that it will fall off and crash but if it manages to cling to the cliff and get to stable ground, it's a big deal. So, value store, unit of account.... some other gainful employment this technology can create by blending it together with other things.... Any way for bitcoin to be useful at this point helps it cling to the cliff.
