I think a lot of people hear "Digital Currency" and think 'something like Apple Pay', when Bitcoin's competition is closer to ACH/wire transfers.
It's not a tech that everyone needs to use, and most people will pay an expert to use it for them. But if successful, could be a valuable medium for receiving payments from low-trust entities.
For example, if a stock exchange accepted Bitcoin for funding accounts, you could get your account up, funded and ready to trade in less than an hour. Most stock exchanges now take several days for funds to clear.
