I am interested in the coins that have real life use case, which can be used even by people who have no crypto experience or interest. If you know any, can you please explain it with a few words?

Not to shill but just as an example:
LOC - Lockchain: The developers claim that anyone will be able to book hotels with 15-20% lower prices than booking.com using either fiat (LOC conversion is in the background, so user doesn't need to know or care) or LOC (3% more discount if LOC is used).

Thanks!
