To be honest, I don't see any upcoming potential IEO/ICO's. Thise already happend they are failed we can say. All of them dumped huge after listed and that's the reason why investors are discourage from IEO/ICO investments. If projects are not able to gain trust from investors then there is very low chance of success. There should be something new trend to attract investors. Otherwise negative impacts will not change.
Take an eye on upcoming Harmony (ONE) on Binance. Do you see crazy pumps of CELER, MATIC and FET in recent days? I don't talk about real use or technique features of those tokens. I'm talking about investing. Binance won't tarnish its image by letting investors down.
I think Harmony is a great IEO to invest to because ALL OF THOSE PROJECT THAT COMES TO BINANCE HAS AN AUTOMATIC PUMP. Lol, Like what you have said, CELER, MATIC, FET there were pumps on these types of coins. Probably Harmony might be the next coin of binance that will pump. With these hypes, sure it will.
