I am sure that most people (like me) have heard about cryptocurrency but still get confused by what this actually involves. However, the more you read about this, the more informed you get. It is more or less like an IPO, only that in the former's case, the companies involved often don't undergo serious credibility checks. Since there are many of these companies operating out there, what do you suppose should be critically looked at before investing? For instance, should the lack of an SSL certificate in a website raise eyebrows?
