Yeah , this is the reality that we should invest our money only those icos products if they are working.
In my whole career of the Bitcoin Field I seen that many ICOs launched their ico before develop the coin and launched their coin after two years , so here we can say that they have no guaranty that how much time will take to launch the coin or how much time to enter the coin in the exchange and market and also their price mostly get down ( in my case mostly ) .
So here more better is to get information about them that who is operating and how much chances that coin will make a better place in the market and what is technology behind the coin algorithm ( stable or not ) And what is economical support that the coin have .
