I think to successful in an IEO we must be lucky cause it's very difficult to buy coin/token in IEO cause number of investors is very huge while number of coin/token in IEO is limited. But I think you should make a team about 4 - 5 persons, maybe it'll help cause as I can see there are so many teams created to buy token/coin from IEO and it worked although amount of token/coin they could buy wasn't so much.
