Have you ever supported, bought or mined a coin that died later on? Why did you support it? What did you learn from it?
I have not get trapped into such a situation and hope the same continues in future because the feeling you get after that is very bad.Sometimes we know that this project is not good and not going to successful but still out of greed we get influenced by that and get struck in dead coins situation. So its better to look for a sound team with good backup and coin with many utilities.
