IEO isn't bad, but the road is too excessive. Remember this could be a new way for scammers to commit fraud. we still have to be vigilant and don't trust too much even if it's in a big exchange though.
IEO is a hype investment lately but it is difficult to invest there because the duration is quite short, if you want to buy better, just wait when the token can be opened in the trade.
I also hope that the IEO will now tackle scammers but I am sure the IEO in the big exchange will become big investors to rise again.
