ICO could be a good investment, or it could be a total disaster for you. Always do your own research before investing on it, but well, there is no safe investment as well,right? There are lots of potential ICO, but I believe most ICO will be a rubbish coin eventually. Always check their whitepaper, roadmap, circulating supply, and social media. This is the easiest way to check it (even though it's not 100% means you're safe though). I hope you invested on right altcoins!!
and i think we must add additional information from profesional such as icoratings etc
after we understand about that above, it's time to get good entries
earlier buyer always get highest bonuses
for me, if i loose the chance i always wait for that token to enter the exchanger to buy
