Pharmaceutical companies. They seem to have a great future. The population in most industrialized countries is aging, and many require medicines chronically. On the other hand, I have the impression that this is not going to be the only pandemic that we have in sight in the next few years and there the pharmaceutical companies are going to play an important role.
I don't think that they have the most profitable industry, most of the money that they earn from selling drugs are covered by insurance which means that they do not get the full profit when it comes to selling pharmaceuticals. The best companies to invest in beside crypto industries is technology giants or start ups that could go big someday, technology is the frontier of mankind and hitching on them for profit will be of big help in return.
