i see many cryptocurrency exchanges have IEO launch, but it doesn't mean the projects launched are good.
We must do many times of research about the project in every exchange, even IEO in binance should be researched properly.
Of course, investors are always advised to perform extensive researches on projects before joining because not all IEOs on the market are legit especially the ones hosted on the newly launched exchanges. I trust IEOs on big exchanges like Kucoin, Binance, however, I do perform the research.
