list of things to consider before investing
Is it a scam?
Is it listed in exchanges?
Is it a new or older project?
If project is older; is there active development?
Try the product and compare to other similar projects.
What innovation does this project bring that is unique and what are its other selling point.
Is the project well funded?
Is their a team or a single person leading the project?
How many strong competitors are there in this field?
What is the likely potential payoff?
Is the product useful?
Does the developer have a clear roadmap and mile stone. Does he keep it?
Are there any other points that need to be considered, any suggestion would be appreciated.
I think even when considered all the points you are telling will be more safe to invest in that coins and you wont get scam or cheated. The points you refereed are ok for some extent but the main point is the patience in investing or trading because if you are thinking that you are investing today and tomorrow itself you will get the profit is stupidity.
