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 exchange platform are good to me, and honestly I never experience to join yet in the IEO under Binance and Huobi.
In fact, I am hunting a project campaign that will run IEO under by these exchange, but mostly in which saw was always under by Latoken,
vindax, Bitforex and Exmarket so far.
