Smart investments are needed. Do your own research and due diligence. Yet, everyone wants to jump in straight away - some kind of 'pump and dump'. Those strategies can work on 'joke' coins, so someone can make some cash. But, when it happens to coins that have a purpose it isn't funny. It has happened to Steem Dollars (SBD) only last year.
The markets are down today, but we are not worried. Hopefully, it will take out some of those who are not in here for the long-term.
Smart is the key. I think most invest on gut feeling. Like you say, do your own research and due diligence.
Markets have been a bit quieter since the festive period i've noticed only a few coins really jumping out. I'm sitting paitently.
