Can Bitcoin solve the worlds problem?
I think however bitcoin is good in our economy, it can't solve the greates problem of humanity. The problems of the people is poverty. Poverty that tends to death, criminalities and under developing society. The unlimited wants and needs of the people to the scarce resources are the problem of our era. Hence, bitcoin is helpful for some but not in all. We expect that no one in this world can change or solve the problem of humanity.
