Most of these shitcoins are the ones that give more Return on Investment than the reliable ones based on the current market condition but it is highly advisable not to leave any out, I mean, you have to invest in coins with viable projects and still take advantage of the ones that are shitcoins to make money before dumping them, just that one has to dump them as quick as possible.
but there are really investors who would really tend to go beyond borders which trying out to put up money on new projects hoping that they can get in as early as possible and make huge profits later on when the project do gain support but these chances are getting slimmer day by day because most projects now are completely trash.
Sice you already talk about confidence , maybe those kind of investors that invest on new projects are confident enough with their decision . for me there is nothing wrong it . you only know whats good for you the most so better if you can follow your instincs than following the others .
Just remeber , dont put your eggs in one basket especialy to those new projects because they are more riskier than the top rank coins .
