Yeah IEO is a new method of fund raising and now is veru poppular. I've never use Latoken for invest to IEO project, i am prefer to use Binance and Okex because this platform is the best platform and trusted.
Crowdfunding via ICOs is the past trend, that was hottest in 2017. This year, the hot trend is IEOs which are perfect tools to raise funds via crowdfundings. Binance and OKEX are biggest exchanges, so there are no issues with their IEOs, sure. However, for other exchanges (smaller, young) and their IEOs, investors should be careful and do detailed analysis & research before spending their money to invest.
