If you're really interested to invest in ICO's, i'll recommend you to make your own research about the ICO that you'd like to invest. Don't accept any suggestions from other investors, because you're the one who are investing not them. But always remember that in cryptocurrency no one can assure you that you will earn from it by just buying some cryptos, that's why you just have to invest an amount that you can afford to lose, to avoid of regretting later.
