Yes, there is something negative at this time and it is the low price of Dash and the other cryptocurrencies in the market. However, it may be a project that will be taken up later
It really is a great proposal. I am a marathon runner and I know the impact of such an event in the locality, which would be very positive for Dash. If I got a Caracas-San Francisco flight that could be paid for in Dash, I would participate in the marathon. Regards.
