It can be but it is not always an exact science what will happen to these so called new coins. They are very risky to put money in, so when you invest in them you should have it in mind that there is a high chance that these new coins will be unlisted which means that you would be losing money from it. You do stand to make a lot of money if the price of the coin you invested in ends up going up.
Not all coins is good and profitable like this in the down market new listed coins have a more chance of making a bad move while some of the big ICO in the past, storiqa, wanchain and many more is much big risk once and for all it has already a big gains and some of it had a more bonus price hype.
The answer is yes and no at the same time. If it's a solid project, it's nice to buy it when it get listed newly. If it's a moderate project, you should wait more to understand the behavior of that project.
