I have made investment into alternative coins based on the time of investment usually i traded alternative coins on ethereum, ethereum classic, Cardano/ADA, Waves coin, ripple, enjin coin, xml, litecoin, dashcoin and Tron but i have made some investment into the ICOs projects for long term investment, they have big chance for me to getting large of profit with small amount of money than another alternative coins, so actually i don't just invested on top 10 alternative coins now, but i choose the ICOs projects too.
I completely agree with you that there are some ico companies that are quite promising and can really bring a good profit in the future. But the fact is that how to study information and how to select really high-quality projects, and not get caught on scammers? I think that in this regard, you need to do a lot of work, so that everything turns out qualitatively.
