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.
Although that I would respect the opinions of other people in this wonderful community, I would go for Binance IEO.
In my own observation, a lot of projects that are doing IEO on Binance are successful. Because of Binances reputation and being the most popular crypto exchange in the world, that would make sense.
The only setback for us in doing IEO for them is their expensive fee. Even listing fee is so expensive nowadays, but they deliver very well mostly in peoples expectations.
However, Binance isnt perfect either and kinda vulnerable to hacking like last time. Huobi is also great, but Ive never tried their exchange yet.
