Many other projects are a lot better, and if you missed one, I think you should keep looking for other projects. Choose the IEO projects at the big exchanges like Binance, Okex, Huobi, Gate .. Surely those projects will bring you profit.
the quality of the exchange does not guarantee a profit. now the hype around IEO has already passed and now all investors have become smarter and do not invest in every project that conducts IEO on one of these exchanges
