Some exchanges are really going to help anyway as obviously; the ones available are even finding it hard to accommodate more users. However, some of them really do not even need ICOs and most of them also come to just scam a lot of users at the end of the day.

Just like the OP have mentioned, the crypto ecosystem right now is full of shit coins and greedy investors as well as devs, but one thing I believe is that at the end of it all, most of them will be thrown away like a piece of shit that they are.
