There are many reasons! Diversity of investment is something good. Safety and security can be bolstered by using it (the right way) and it's ofc an interesting growth market - it also got a novelty touch and gives the user more independence! I guess in the future there are going to be even more options how to implement the technology into our daily life - Ticketing services like the Cultural Coin are a good start but i expect there will be many different usage opportunities to come. ^^ We are just scratching on the surface.
