Know a days blockchain is a trend that many projects, apps, website that offerd the service of bitcoin, it because transactions or paying bills, and others become easy beacuse of bitcoin. But for me i think blockchain not that so perfect for a solution to a certain problem, but it maybe contribute and a tool for improvement of a country's problem. Example in africa they developed a health app which focuses to their main problem and that is health care and that app is AfriHealth as we all know africa is not that well equipped when it comes to many field specially in health care but this was surprisingly that they developed a health app that powered by blockchain and i would say it was very well done project, its smart to use blockchain because its popularity. And with the use of this health app project, they can attract investors and if theres investment the economy of africa will grow also the health field will improve because of the app, it is worth to invest in this kind of project why? Because this app provide a wonderful health services such as, purchase medicines across countrys, access your own medical records, set an appointment in a doctor near hospital place in your neigborhood, and in case of emergency the app can be used to call an ambulance that is near to your place and also purchasing a insurance plan and many more. So i can say that this app that use the influence of bitcoin can make a country developed and to improve and it can benefit other country also because, yes easy transaction and access to this health app.
