You must be careful when choosing an ICO to invest to. I myself is a victim of ICO scam but I just lost a small amount to it. The information they give is not enough to judge that the ICO you are participating with is legit. You must dig more information on the ICO to ensure that it is a legit ICO.
With many it happens. Well, that was not a big sum. If you want to invest the next time, use the icodrops.com website. This site will greatly reduce your chances of getting on scammers.
ICO listing website like your which have experienced rating from expert really play a role in reducing the chance to trap in the scam ICO I am also using these sites especially I use ICOschedule and ICObench for looking that which ICO is going better and which ICO do not have rating. I invest only when the rating increase the 80% of the rating marks.
