Hi there.
In my opinion, I like Huobi's IEO than Binance's IEO. Right, Binance IEO require the smaller days of holding, but the price of BNB is dumping everyday. But HT isnt, it's price increase everyday, and hard to dump (except BTC dump, all alts will dump). And the Huobi's IEO help us better profit too. From x4-x10 until now, but with Binance's IEO, some IEO is having x0.5-x2 now.
Both exchangers are large exchangers with good reputations in the eyes of investors. Everyone has different views about the exchangers that are best for him and as long as IEO is still profitable, I think both BInance and Huobi are as good
