However, until now unfortunately there is no health and data-based cryptocurrency project that is able to compete with other companies... the background of each developer may be a big influence on this belief... considering that the majority of the industry that is present in cryptocurrency is used as a tool to bring in income, while people who are experts in the health sector feel it is the opposite...CMIIW
