But chances of truning those 100 dollars into 1000 dollars has dropped recently a lot mate! There is no way that any ICO might just turn your 100 bucks to 10x in short period of time these days. Those golden days has gone already and now is the time where we need to take lot of effort to find a perfect ICO to invest in. Almost more than 70-80% of the ICO seem to be scam one and thus you will need more than 100 ICO to be joined per month to get hit by at least 20 of the good ICO's around the globe. However that does seem to me very impossible these days.
Its not that risky if you invest into them when they are in the exchangers.
