Traders always want to invest in the best currencies and trade itself for getting good profits but investment on new to the upcoming currencies will not give any assurance for the profits that's why taking the decision into a risk will little bit not important in this type of situation but everything is going proper then you can definitely got some success also
I am feeling like its pure marketing even if these coins are listed there wont be much effect till community acc or the project . Till that its just another try to push the coins.
That's the focus of every ICO because they want to attract investors, and I know it will not affect their real product. Traders are not investing during the ICO period, they just wait for the exchange listing and yes the risk with ICO right now is very high and so many failed projects. The three ICO above is quiet not good to me, so many ICO about the infrastructure and real estate and until now they are still not working well.
Traders have always known that there are no guarantees especially for newly listed coins. ICOs nowadays have little chance of getting good following simply because all the scams and non-legit projects have tarnished the reputation of ICOs. And most of the time the listed coins take a lot of time before having actual trading values.
