The WSJournal article says if BTC is to change dollar, its current value is 0. Plus the ways of possible transactions with BTC is very limited and it requires spending lots of energy (who can explain the part with the energy spending?).
The transactions don't require energy from the person sending or receiving the Bitcoin. The energy is spent by the people confirming the Bitcoin, the bitcoin miners.
Do you have a link for this article that you can share? Saying that "if BTC is to change dollar, its current value is 0" literally makes no sense. Help us by giving us more information.
Thanks.
