If you do not want to get to the scammers, then take part in the IEO only on well-known and proven exchanges. It seems to me that this direction will live as well as the ICO.
Avoiding or lessened the chance of being scammed if you wanted to participate with this type of investment, taking your chances to invest inside binance would be the smartest thing to do, tough but with those previous results where most investors received more than doubled after participating from the IEO launchpad.
Of course. It is a choice of anyone here whether to invest in new projects like IEO or to invest in some reputable one like binance or in other established projects. IEO is still a way to fund raise money and we can't control scammers to find a way to enter IEO. Though it is hard to choose where projects to be invested but taking a risk will always give you a 50-50% chance of being successful or not.
