1000% returns ooohh fook me its time to go balls deep in the next ieo....
Each IEOs are different, Harmony really did give great returns doesn't mean the next one will give return like that, By the looks of current market things are going bad for altcoins. So carefully plan your investments.
It is true that not all IEOs provide returns, perhaps the return of harmony yesterday was very big because their team was very good at developing their project. We cannot just invest in the IEO just because it was launched at Binance. Even if the project is launched in exchange for under binance ranking it does not mean that it is not successful because a project has its own strategy and the Binance IEO does not guarantee we get a return.
