I would stick with some of the established coins including BTC, ETH, XLM, NEO as your first choices for starting an investment. ICO coins have done really badly during 2018 and unless the coin is ready to launch their platform and not make you wait through 18 months of development I would give them a wide berth.
For sure, it is better, for the time being Investing into BTC, ETH and others. I also realize that in recent months ICO coins have been unpredictable and expected. But there are still good and potential for ICO. If the ICO project is very good. If to hold it temporarily it's better for coins. And for ICO you should prefer good projects like Gigzi.
