I think IEO is more safe than ICO. IEO minimize the risk of investment.ICO investment is one kind of gambling but IEO pure stock market.So now my investment prefer to IEO.But it's true for good project ICO or IEO don't matter.
It is true that compared to the current ICO the IEO is better and the risk is smaller than fraud but it is still risky if we are not careful.
Actually it's almost the same, but I see some people have moved to invest in the IEO, hopefully ICO can be better in the future.
