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.
In a quest to know the reason that made you say that Huobi IEO is better, I discovered that your thought was on the profit made. If that is your thought, then I ill say that you might be wrong, because a lot of IEOs have been held on Binance and I am not sure if Huobi has done even what of what Binance has been able to do. The Binance I know of brings in profit for IEO investors because they have a lot of traders trading on the exchange.
