As we live more and more in the city and space in downtown is precious, there is less and less parking space. It's hard and expensive to get your own car when you live in the city (parking lot, gasoline, insurance, maintenance...). So the HelbizCoin solution is great in order to improve the quality life in city, less pollution with and more options to mobility.
Moreover, for car's owner, on average, cars are parked 95 percent of the time, so it's a good way to make some money with your car by sharing it.
Good business opportunity and as you say @danizaharie, the collaboration with many leading partners is another great point, trust is essential.
