There is no big differece between IEO and ICO ,IEO´s are not safer.
In some countries there are some higher regualations for ICO´s or ICO´s are even restricted and if you can´t reach it what you can do?Make an IEO,simple.
There i no real protect for investors.
Also,lot of IEO doesn´t even make any private sales,all those coins are belong to few people.That opens the door for huge manipulations,only that few people wins.
Situation for investors keeps the same,no matter if ICO or IEO,good research saves you money.Same for hunters.
I´m staying with Bitcoin and some valuable Altcoins with deep solid ground.Now it´s time to pick up some future Amazons,Google´s or Alibaba´s
