There is some projects going on which looks very promising and probably will bring its investors serious profits.
For example ICONOMI ICO is active right now, you can check their announcement thread here:

i don't think that is such a good idea so i discourage you to do it also.
many of these ICOs are bad and many look good on the surface but turn into scams so fast you can't turn your head around and say what.
investing in ICO means investing in something that is not yet take any shape, it would be a great gamble so if you want to gamble then go for it.
but trading on the other hand means you can see the coin after it is released and it has shown its weaknesses and powers and also you can see the volume, the interest people shown and many other stuff and make your investment then.
It really depends on people if he really wants to invest on ick or not since they are the one who's entitled with their money and there are some potential ICO coins are existing today, but as you say there are many scam coin existing there but you can really define wich is scam or not since some of them are givinf so much bunos and to good to be true offers to their prospects. And if OP wants to trade a coin who's existing on exchange well he must try to trade xaur,xhi,stratis and draco.
